      Data Structures

      Generic Red Black Tree

      +

      The file rbtree.c contains the source code for a generic red black tree. This data structure is capable of storing any kind of data and its defined in rbtree.h as:

      +
      +
      +tree_root
      +
      + +
      +
      +struct sroot
      +
      + +
      typedef struct sroot{
+   struct stree_node* root;
+   void* (*key)(struct stree_node* node);
+   int64_t (*compare)(void* keyA, void* keyB);
+}tree_root;
+
      +
      +

      There are two things to notice here. First, this is only the root of the tree and points to the first tree_node of the rbtree. Second, it contains two function pointers. The first points to a function, which receives a tree_node and should return a pointer to that node’s key. The second is a pointer to a compare function, which compares two keys and should return:

      +
        +
      • A negative integer if the first key is smaller than the second.
        • +
      • 0 if the keys are the same.
        • +
      • A positive integer if the first key is bigger than the second.
        • +
      +

      These pointers must be provided by the user. Why do we need these pointers? Because the data stored in the rbtree can be anything, but we still need to know how to sort it. Nevertheless, if you wish to use this data structure as a container and don’t care how things are sorted, you can always use the method new_simple_rbtree().

      +

      Each node in an rbtree is called a tree_node and is defined in rbtree.h as:

      +
      +
      +tree_node
      +
      + +
      +
      +struct stree_node
      +
      + +
      typedef struct stree_node{
+   void* node;
+
+   uint8_t color;
+
+   struct stree_node* parent;
+   struct stree_node* left;
+   struct stree_node* right;
+ }tree_node;
+
      +
      +

      There’s not much to say about this structure, the only thing relevant is the field node, which is used to store the actual data. The other fields are used to keep the rbtree intact.

      +

      Finally, there’s one more structure, which is defined in rbtree.h as:

      +
      +
      +tree_iterator
      +
      + +
      +
      +struct siterator
      +
      + +
      typedef struct siterator{
+   struct stree_node* current;
+}tree_iterator;
+
      +
      +

      As the name implies, this structure is an iterator to the tree nodes.

      +

      As a final note, remember that we provide functions to destroy our structures, but the actual data must be destroyed by you. Do not use iterators for this purpose.

      +
      +

      Function description

      +
      +
      +tree_root* new_simple_rbtree()
      +

      This function creates an rbtree, which sorts the data acording to its memory pointer. This function should be used when you just want the rbtree to behave as a container, +but you still need O(log(n)) when accessing the data. Keep in mind that in order to retreive the stored data, you need to know it’s memory pointer.

      +

      The return value is a tree_root structure.

      +
      + +
      +
      +tree_root* new_rbtree(void* (*key_function_pointer)(struct stree_node* node), int64_t (*compare_function_pointer)(void* keyA, void* keyB))
      +

      key_function_pointer A function that should return the address of the node’s key.

      +

      compare_function_pointer A function that should compare two keys and return values as described above. It receives the addresses of each key.

      +

      This function creates an rbtree, which sorts the data according to the given functions. The following example shows how to create an rbtree to store integers.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      + +
      +
      +void* rb_tree_insert(tree_root* root, void* node)
      +

      root A pointer to the tree root where to insert the data represented by node.

      +

      node A pointer to the data, which will be inserted in the tree.

      +

      As the name implies this function inserts data into the rbtree. In the eventuality that the inserted value is already in the tree, it will be replaced and a pointer to the older value is returned. This is done so the user can free the space stored by that data. The following example shows how to insert integers in an rbtree.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   int a = 9, b = 6, c = 10, d = 6;
+
+   rb_tree_insert(rbtree, &a);
+   rb_tree_insert(rbtree, &b);
+   rb_tree_insert(rbtree, &c);
+   int older = *((int *) rb_tree_insert(rbtree, &d));
+
+   //don't free older because it was "alloched" by the compiler.
+   printf("Found a %d already stored in the tree.\n", older);
+
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      + +
      +
      +void* rb_tree_delete(tree_root* root, void* key)
      +

      root A pointer to the tree root where to delete the data with key pointed by key.

      +

      key A pointer to the key of the node to be deleted.

      +

      This function deletes a node from an rbtree. If a node with a key equal to the one pointed by key does not exist, NULL will be return. However, if such a node is found, then a pointer to the data is returned. This is done so the user can free the space used by that data. The following example shows how to use this function on an rbtree that stores integers.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   int a = 9, b = 6, c = 10;
+
+   rb_tree_insert(rbtree, &a);
+   rb_tree_insert(rbtree, &b);
+   rb_tree_insert(rbtree, &c);
+
+   int d = 10, stored;
+   stored = *((int *) rb_tree_delete(rbtree, &d));
+
+   //don't free stored because it was "alloched" by the compiler.
+   printf("Found a %d stored in the tree.\n", stored);
+
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      + +
      +
      +void* search_rbtree(tree_root root, void* key)
      +

      root The root of the tree where to perform the search.

      +

      key A pointer to the key of the node to be searched.

      +

      This function searchs an rbtree for a node. It returns NULL if nothing is found, or the data stored in the tree with a key equal to the value pointed by key. The following example shows how to search a tree that stores integers.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   int a = 9, b = 6, c = 10;
+
+   rb_tree_insert(rbtree, &a);
+   rb_tree_insert(rbtree, &b);
+   rb_tree_insert(rbtree, &c);
+
+   int d = 10, stored;
+   stored = *((int *) search_rbtree(*rbtree, &d));
+
+   printf("Found a %d stored in the tree.\n", stored);
+
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      + +
      +
      +void destroy_rbtree(tree_root* root)
      +

      root A pointer to the tree to be destroyed.

      +

      This function destroys an rbtree. Note that this doesn’t free the user stored data. The following example shows how to use this in a tree that stores integers.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   int a = 9, b = 6, c = 10;
+
+   rb_tree_insert(rbtree, &a);
+   rb_tree_insert(rbtree, &b);
+   rb_tree_insert(rbtree, &c);
+
+   destroy_rbtree(rbtree);
+   //We do not need to free the stored data because it was "alloched" by the compiler.
+
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +

      Notice that running the command

      +
      valgrind --show-reachable=yes --leak-check=full ./test
+
      +
      +

      produces the ouput:

      +
      ==1188== HEAP SUMMARY:
+==1188==     in use at exit: 0 bytes in 0 blocks
+==1188==   total heap usage: 4 allocs, 4 frees, 72 bytes allocated
+==1188==
+==1188== All heap blocks were freed -- no leaks are possible
+
      +
      +

      Which means that there are no memory leaks and you should always use this function to free the space stored by any rbtree you use.

      +
      + +
      +
      +tree_iterator* new_tree_iterator(tree_root* root)
      +

      root A pointer to a tree root, which the iteration will be performed.

      +

      This function creates an iterator to an rbtree. Note that when you create an iterator, you should not insert or delete nodes from the tree before the iteration is over. Otherwise, the behaviour of the program will be unpredictable. It returns pointer to the created iterator. The following example shows how to create an iterator for a tree that stores integers.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   int a = 9, b = 6, c = 10;
+
+   rb_tree_insert(rbtree, &a);
+   rb_tree_insert(rbtree, &b);
+   rb_tree_insert(rbtree, &c);
+
+   tree_iterator* it = new_tree_iterator(rbtree);
+
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      + +
      +
      +uint8_t tree_iterator_has_next(tree_iterator* it)
      +

      it A tree iterator created by calling new_tree_iterator().

      +

      This function returns 1 if there are more elements in the tree to be iterated. The following code shows a simple usage of this function.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   int a = 9, b = 6, c = 10;
+
+   rb_tree_insert(rbtree, &a);
+   rb_tree_insert(rbtree, &b);
+   rb_tree_insert(rbtree, &c);
+
+   tree_iterator* it = new_tree_iterator(rbtree);
+
+   if(tree_iterator_has_next(it))
+     printf("There are still elements to be iterated.\n");
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      + +
      +
      +void* tree_iterator_next(tree_iterator* it)
      +

      it A tree iterator created by calling new_tree_iterator().

      +

      This functions returns the current element pointed by iterator it and advances to the next element in the iteration. This function should be used with tree_iterator_has_next(). Note that there is no guaranty about the order of iteration. The following code shows how to use it.

      +

      Example:

      +
      #include <stdio.h>

+
+void* key_address(tree_node* node){

+
+   tree_iterator* it = new_tree_iterator(rbtree);
+
+   while(tree_iterator_has_next(it)){
+     int d = *((int *) tree_iterator_next(it));
+     printf("%d\n", d);
+   }
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      + +
      +
      +void destroy_iterator(tree_iterator* it)
      +

      it A tree iterator created by calling new_tree_iterator().

      +

      This function frees the iterator pointed by it. The following example shows how to use it.

      +

      Example:

      +
      #include <stdio.h>
+#include "rbtree.h"
+
+void* key_address(tree_node* node){
+   return node->node;
+}
+
+int64_t compare_integers(void* keyA, void* keyB){
+   return *((int *) keyA) - *((int *) keyB);
+}
+
+int main(){
+   tree_root* rbtree = new_rbtree(& key_address, & compare_integers);
+   int a = 9, b = 6, c = 10;
+
+   rb_tree_insert(rbtree, &a);
+   rb_tree_insert(rbtree, &b);
+   rb_tree_insert(rbtree, &c);
+
+   tree_iterator* it = new_tree_iterator(rbtree);
+
+   while(tree_iterator_has_next(it)){
+     int d = *((int *) tree_iterator_next(it));
+     printf("%d\n", d);
+   }
+   destroy_iterator(it);
+
+   destroy_rbtree(rbtree);
+   return 0;
+}
+
      +
      +

      You may compile it with

      +
      gcc -o test <above_source_file> -I<folder path where rbtree.h is kept>
+
      +
      +
      valgrind --show-reachable=yes --leak-check=full ./test
+
      +
      +

      produces the ouput:

      +
      ==4432== HEAP SUMMARY:
+==4432==     in use at exit: 0 bytes in 0 blocks
+==4432==   total heap usage: 5 allocs, 5 frees, 76 bytes allocated
+==4432==
+==4432== All heap blocks were freed -- no leaks are possible
+
      +
      +

      Which means that there are no memory leaks and you should always use this function when iterating.

      Document Object Model

      +
      +
      +dom_node
      +

      Abstract representation of an xml node.

      +
      + +
      +

      DOM

      +

      After the parsing of the xml is done, a DOM structure is created and +can be accessed through a global variable denominated “document”. +Bear in mind that this variable is dependent of the current parser. +In other words, if the parser module changes, then the variable name +may also change.

      +

      The DOM structure is a tree, where each node is an xml element. Since +the input xml has already been validated we know it has only one root +, so the document variable will point to a single node in the dom +tree, the root node (This can be accessed through document->root).

      +

      The dom structure provides flexible and extendable xml document +handling. It has the capability to add, remove and modify elements in +the xml. The next section will explain in deeper detail the DOM +module functions.

      +
      +
      +

      DOM functions

      +

      To create a dom structure, the function new_document should be +called. If the input xml has the form:

      +
      <?xml version="1.0"?>
+<root>
+  ...
+</root>
+
      +
      +

      And you wish to store the <?xml version=”1.0” ?>, you can do this by +creating a dom_node with the name “xml” and attribute “version”. This +dom_node must be passed to the function new_document. This is done to +keep the dom structure simpler and with only one root. As we said +before, this implementation makes the assumption that the xml has +already been validated.

      +

      Although we provide in the header file the structures dom_node and +doc, thus exposing their implementation, we highly recommend that you +use the proper access functions to obtain each field. If we change +the structures, we will not change the functions’ signature, only +their implementation if needed. By using the access methods, you +won’t need to change any code done. For the same reason, we recommend +that you use the proper setter functions to store the values in each +node.

      Special Macros

      +

      The file macros.h contains macros used all over our project. These macros were made to ease our pain in coding some things. This page describes and shows how to use them

      +
      +

      alloc

      +

      This section describes the macro

      +
      +
      +alloc
      +
      + +

      Ever get tired of calling malloc and check if the return address is a valid address, and if not print an error message and exit? The alloc macro can do all of this for you. It depends on the function __alloc():

      +
      +
      +static inline void* __alloc(void* x)
      +
      + +

      It is defined as:

      +
      #define alloc(type, how_many)                           \
+   (type *) __alloc(malloc(how_many * sizeof(type)));
+
+static inline void* __alloc(void* x){
+   if(x)
+     return x;
+   log(F,"malloc failed.");
+   exit(1);
+   return 0;
+}
+
      +
      +

      The key to this macro resides in the __alloc() function. It receives the address returned by malloc() and checks if it is valid. If not, then a log message is printed and exit() function is called. The following example shows how to use this function to allocate an array of 100 characters:

      +
      #include <stdio.h>
+#include "macros.h"
+
+int main(){
+  char* buffer = alloc(char, 100);
+  return 0;
+}
+
      +
      +

      You may compile it with

      +
      +
      gcc -o test <above_source_file> -I<folder path where macros.h is kept>
+
      +
      +
      +

      Notice that you won’t even have to bother with casting it to the right type.

      +
      +
      +

      log

      +

      This section describes the macro

      +
      +
      +log
      +
      + +

      Ever filled your code with printf() functions to debug it? And when you’re done with it needed to erase them? The log adds proper debug messages and doesn’t need to be removed when the code is functional. Let’s look at its definition:

      +
      #ifdef DEBUG
+#include <stdio.h>
+#define log(level, format, ...)                                 \
+  do{                                                           \
+    fprintf(stderr, "%s  %s:%d: ", level, __FILE__, __LINE__);  \
+    fprintf(stderr, format, ## __VA_ARGS__);                    \
+    fprintf(stderr, "\n");                                      \
+  }while(0)
+#else
+#define log(level, str, ...)
+#endif
+
+#define I "INFO"
+#define W "WARNNING"
+#define E "ERROR"
+#define F "FATAL ERROR"
+
      +
      +

      First note the macros for I, W, E, F at the bottom. These are merely alias for the level of severity, you may use any other. The log macro prints messages to the stderr and is able to format strings according to printf() format options. Consider this example:

      +
      #include "macros.h"
+
+int main(){
+ log(I, "Printing info\n");
+ return 0;
+}
+
      +
      +

      If we compile and run this example with the option -DDEBUG we’ll get the following output

      +
      +
      Printing info
+
      +
      +
      +

      If such option is not passed to the compiler, them no output will be shown. This happens because the macro is not created. What this means is that you can actually fill the code with logging messages and debug it, and when you’re done just compile it without -DDEBUG . The result is a binary file that doesn’t contain code related to debug messages, thus is smaller than the debug version. However, if you need to debug it again, you can always recompile it with the debug flag.

      +

      Notice that file name and line number are printed as well, which helps you pin-point the location of the print and check what may have been the cause of the problem.

      +

      Querying

      +

      Querying xml nodes to provide quick random access to inner nodes is +implemented through CSS3 selectors.

      +
      +

      Note

      +

      CSS stands for +cascading style sheets, it is primarily used for styling (x)html documents +as method to separate content from presentation.

      +
      +

      The CSS3 selectors specification is a W3C proposed +recomendation widely implemented by most modern browsers, it has also been used, +in its current and earlier forms (CSS and CSS2), by web developers for over 13 +years.

      +

      The W3C recomendation does not tie CSS rules to the presentation of of (x)html +documents, in fact it does define it as a query language capable of selecting +xml/html nodes. With the rise in popularity of AJAX technologies several +javascript libraries became widely used, these libraries (most notabily +JQuery) first proposed the utilization of CSS rules +not only for presentation but also to help manipulation and transversion of the +DOM.

      +

      This library embraces CSS rules as a better/simpler alternative to manual +transversion as well as other W3C recomendations such as +XPath and +XQuery.

      +
      +

      Selectors

      +

      The function xmlquery_query is defined to help filter and match nodes in the +DOM tree:

      +
      +
      +generic_list* xmlquery_query(const char* pattern, dom_node* root)
      +
      + +
      +
      +dom_node* xmlquery_query_one(const char* pattern, dom_node* root)
      +

      This is a helper function designed to facilitate selection of single nodes. +Selects the first node returned by a given query, it is equivalent to the +following code:

      +
      dom_node* single = NULL;
+generic_list* l = xmlquery_query(patterm, root)
+if((l != NULL && l->count > 0)
+    single = (dom_node*) get_element_at(l, 0);
+
      +
      +
      + +
      +

      Introduction

      +

      Node selection is implemented as a pattern string to be matched against a +DOM tree. The pattern string matches some number of nodes that are +then returned as a flat list.

      +

      A pattern example:

      +
      foo
+
      +
      +

      this simple pattern matches all nodes named foo. Upon matching the DOM tree +with this pattern, a reference to every node named foo would be returned. +Independent of their position in the tree. Returned references may be +manipulated, rearanged or deleted.

      +

      Pattern strings match dom nodes in three different realms, according to the node +name (as we’ve seen), according to the node attributes and according to +pseudo-filters, a special kind of selectors aware of the node context.

      +
      foo[attr='bar']:only-child
+
      +
      +

      A more complex selector, this selector will match nodes with the name foo, +with an attribute named attr with the value bar, and the node must also be +the only child of its parent node.

      +
      +
      +
      + + +

      Tutorial

      +

      The following code shows how to use the library to rename a node in a xml file:

      +
      #include <stdio.h>
+#include <xmlquery/parse.h>
+#include <xmlquery/dom.h>
+#include <xmlquery/serialize.h>
+
+dom_node* node = xmlquery_parsefile("test.xml");
+node_list* q_result = xmlquery_query("@hi[foo=bar]");
+dom_node* n_result = xmlquery_pop_node(q_result);
+xmlquery_set_node_name(n_result, "bye");
+
+printf("%s\n", xmlquery_dom_node_to_string(node, XML);
+
      +
      +

      if test.xml contains:

      +
      <root>
+  <hi />
+  <hi foo="bar" />
+</root>
+
      +
      +

      the resulting output would change the node:

      +
      <hi foo="bar" />
+
      +
      +

      to:

      +
      <bye foo="bar" />
+
      +
      +

      this code will read an xml file in test.xml into our abstract representation +of the DOM (Document Object Model) tree:

      +
      dom_node* node = xmlquery_parsefile("test.xml");
+
      +
      +
      + + +
      +

Why do we need these pointers? Because the data stored in the rbtree can be anything, but we still need to know how to sort it.

This function should be used when you just want the rbtree to behave as a container, - but you still need O(log(n)) when accessing the data. Keep in mind that in order to retreive the stored data, you need to know it's memory pointer. - - The return value is a tree_root structure. - -.. c:function:: tree_root* new_rbtree(void* (*key_function_pointer)(struct stree_node* node), int64_t (*compare_function_pointer)(void* keyA, void* keyB)) - - :c:member:`key_function_pointer` A function that should return the address of the node's key. - - :c:member:`compare_function_pointer` A function that should compare two keys and return values as described above. It receives the addresses of each key. - - This function creates an rbtree, which sorts the data according to the given functions. The following example shows how to create an rbtree to store integers. - - Example:: - - #include - #include "rbtree.h" - - void* key_address(tree_node* node){ - return node->node; - } - - int64_t compare_integers(void* keyA, void* keyB){ - return *((int *) keyA) - *((int *) keyB); - } - - int main(){ - tree_root* rbtree = new_rbtree(& key_address, & compare_integers); - return 0; - } - - You may compile it with - - .. code-block:: bash - - gcc -o test -I - -.. c:function:: void* rb_tree_insert(tree_root* root, void* node) - - :c:member:`root` A pointer to the tree root where to insert the data represented by ``node``. - - :c:member:`node` A pointer to the data, which will be inserted in the tree. - - As the name implies this function inserts data into the rbtree. In the eventuality that the inserted value is already in the tree, it will be replaced and a pointer to the older value is returned. This is done so the user can free the space stored by that data. The following example shows how to insert integers in an rbtree. - - Example:: - - #include - #include "rbtree.h" - - void* key_address(tree_node* node){ - return node->node; - } - - int64_t compare_integers(void* keyA, void* keyB){ - return *((int *) keyA) - *((int *) keyB); - } - - int main(){ - tree_root* rbtree = new_rbtree(& key_address, & compare_integers); - int a = 9, b = 6, c = 10, d = 6; - - rb_tree_insert(rbtree, &a); - rb_tree_insert(rbtree, &b); - rb_tree_insert(rbtree, &c); - int older = *((int *) rb_tree_insert(rbtree, &d)); - - //don't free older because it was "alloched" by the compiler. - printf("Found a %d already stored in the tree.\n", older); - - return 0; - } - - You may compile it with - - .. code-block:: bash - - gcc -o test -I - -.. c:function:: void* rb_tree_delete(tree_root* root, void* key) - - :c:member:`root` A pointer to the tree root where to delete the data with key pointed by ``key``. - - :c:member:`key` A pointer to the key of the node to be deleted. - - This function deletes a node from an rbtree. If a node with a key equal to the one pointed by ``key`` does not exist, NULL will be return. However, if such a node is found, then a pointer to the data is returned.

What this means is that you can actually fill the code with logging messages and debug it, and when you're done just compile it without :command:`-DDEBUG` .

      Tutorial

      +

      In this tutorial you’ll learn how to parse, query and manipulate XML files. We’re going to use the test.xml document, which is an RSS Feed and has the content:

      +
      <?xml version="1.0" encoding="UTF-8" ?>
+<rss version="2.0">
+
+  <channel>
+   <title>RSS Example</title>
+   <description>This is an example of an RSS feed</description>

+     <title>Item Example</title>
+     <description>This is an example of an Item</description>
+     <link>http://www.domain.com/link.htm</link>
+     <guid isPermaLink="false"> 1102345</guid>
+     <pubDate>Tue, 29 Aug 2006 09:00:00 -0400</pubDate>
+   </item>
+
+  </channel>
+</rss>
+
      +
      +

      Every example in this tutorial must be compile as:

      +
      +
      gcc -I<path to our header files> ./libxmlquery.so <source_file>
+
      +
      +
      +

      Lets begin with parsing. The below code shows how to parse the above XML:

      +
      #include "node.h"
+#include "lxq_parser.h"
+
+doc* global_document = NULL;
+
+void read_file(){
+  global_document = parse_xml("test.xml");
+}
+
+void cleanup(){
+  if(global_document)
+    destroy_dom_tree(global_document);
+}
+
+int main(int argc, char** argv){
+  read_file();
+  cleanup();
+  return 0;
+}
+
      +
      +

      Ok so this is a pretty simple file. We’re creating a DOM tree of the above XML document and then cleaning it up. However, this is not a really helpfull example. Lets try to add +the capability of querying the document through the program arguments:

      +
      #include <stdio.h>
+#include "node.h"
+#include "lxq_parser.h"
+#include "query_runner.h"
+
+doc* global_document = NULL;
+
+void read_file(){
+  global_document = parse_xml("test.xml");
+}
+
+void cleanup(){
+  if(global_document)
+    destroy_dom_tree(global_document);
+}
+
+int main(int argc, char** argv){
+  //check if we have exactly 1 argument
+  if(argc != 2){
+    printf("Usage: %s \"query\"\n", argv[0]);
+    return -1;
+  }
+
+  read_file();
+
+  query(argv[1], get_doc_root(global_document));
+
+  cleanup();
+  return 0;
+}
+
      +
      +

      Go ahead and run it with

      +
      +
      ./a.out "@/ti..e/"
+
      +
      +
      +

      It will search the document for all elements that begin with “ti”, have any two characters following it and end with “e”.

      +

      However, we’re able to see the output. Lets add that feature:

      +
      #include <stdio.h>
+#include "node.h"
+#include "lxq_parser.h"
+#include "query_runner.h"
+#include "stack.h"
+#include "serialize.h"
+
+doc* global_document = NULL;
+
+void read_file(){
+  global_document = parse_xml("test.xml");
+}
+
+void cleanup(){
+  if(global_document)
+    destroy_dom_tree(global_document);
+}
+
+int main(int argc, char** argv){
+  //check if we have exactly 1 argument
+  if(argc != 2){
+    printf("Usage: %s \"query\"\n", argv[0]);
+    return -1;
+  }
+
+  read_file();
+
+  list *result = query(argv[1], get_doc_root(global_document));
+
+  generic_list_iterator* i = new_generic_list_iterator(result);
+  while(generic_list_iterator_has_next(i)){
+    dom_node* el = (dom_node*) generic_list_iterator_next(i);
+    char* output = node_to_string(el, XML);
+    printf("%s\n", output);
+    free(output);
+  }
+  destroy_generic_list_iterator(i);
+
+  cleanup();
+  return 0;
+}
+
      +
      +

      Try it with the same query as before and then try to retrieve the element “title” for the “item” title with:

      +
      +
      ./a.out "@/i.../>/ti..e/"
+
      +
      +
      +

      Ok we’re able to retrieve any thing from our RSS Feed. But now, we want to change the title of the element “item” to “no-title”. Let’s do it:

      +
      #include <stdio.h>
+#include "node.h"
+#include "lxq_parser.h"
+#include "query_runner.h"
+#include "stack.h"
+#include "serialize.h"
+
+doc* global_document = NULL;
+
+void read_file(){
+  global_document = parse_xml("test.xml");
+}
+
+void cleanup(){
+  if(global_document)
+    destroy_dom_tree(global_document);
+}
+
+int main(int argc, char** argv){
+  read_file();
+
+  list *result = query("@item>title", get_doc_root(global_document));
+
+  generic_list_iterator* i = new_generic_list_iterator(result);
+  while(generic_list_iterator_has_next(i)){
+    dom_node* el = (dom_node*) generic_list_iterator_next(i);
+    //get the node which has the title
+    dom_node* text_node = get_child_at(el, 0);
+    char* old = set_value(text_node, "no-title");
+    if(old)
+      free(old);
+  }
+  destroy_generic_list_iterator(i);
+
+  char* output = node_to_string(get_doc_root(global_document), XML);
+  printf("%s\n", output);
+  free(output);
+
+  cleanup();
+  return 0;
+}
+
      +
      +

      This concludes the tutorial. We’ve shown how to parse, query and manipulate XML documents.

        Shell

        +

        The shell application is the most simplest application we’ve created to demonstrate the features of our querying engine. It has a simple interface and its purpose +is to load xml files, print them and query them.

        +
        +

        Compiling

        +

        Compiling the shell is very easy. You just type make and it’ll generate a binary called shell.

        +
        +
        +

        Running

        +

        After compiling the shell application, you just need to run the binary file shell without any arguments.

        +
        +
        +

        Interaction

        +

        After running the application, you’ll be presented with a banner and a prompt. You can begin by typing help to see which commands it supports.

        +

        As an example:

        +
        ############################################################################
+#                                                                          #

+
        +
        +

        From here you can deduce what commands we implemented. The gdb command is there just for development convenience. A typical interaction would be:

        Function description

      + +
      +

      Serialize DOM

      +

      This section explains how to serialize a DOM tree into a string. Currently we support three different types of output format:

      +
        +
      • XML - print the DOM tree as XML format.
        • +
      • JSON - print the DOM tree as JavaScript Object Notation format.
        • +
      • YAML - print the DOM tree as YAML Ain’t Markup Language format.
        • +
      +

      To do this we’ve defined an enumerate as:

      +
      typedef enum{
+  XML=0,
+  JSON=1,
+  YAML=2
+} serialization_type;
+
      +
      +

      The serializarion is done throw the function:

      +
      +
      +char* node_to_string(dom_node* root, serialization_type t)
      +

      root The root of the tree to serialize onto a string. Can be any part of the DOM tree.

      +

      t The type of serialization to do. Must be one of XML, JSON, YAML.

      +

      The following example shows how to serialize a document onto JSON format. If another one is desired you can change the type of serialization:

      +
      #include <stdio.h>
+#include "include/node.h"
+#include "include/serialize.h"
+#include "include/lxq_parser.h"
+
      +
      +
      +
      int main(int argc, char** argv){
      +
      doc* document = parse_xml(“some.xml”); +char* json; +json = node_to_string(get_doc_root(document), JSON); +printf(“%s”, json); +free(json); +return 0;
      +
      +

      }

If you want to design a filter that takes arguments, you must use the second signature. + +After defining your filter you need to register them.

    The first one creates a filter that doesn’t take any arguments. If you want to design a filter that takes arguments, you must use the second signature.

    After defining your filter you need to register them. You do this by calling:

    -
    .. c:function:: void register_simple_custom_filter(const char* name, int (*filter)(dom_node* node))
-
    -
    +
    +
    +void register_simple_custom_filter(const char* name, int (*filter)(dom_node* node))
    +
    +
    void register_custom_filter(const char* name, int (*filter)(dom_node* node, list* args))

    Custom pseudo-filters

    The first function registers a simple filter, while the second registers a complex one.

    When you’re done with this you can call your filters just like a CSS3 pseudo-filter.

    +

    When you’re done with this you can call your filters just like a CSS3 filter.

    +

    When your program finishes, we should call:

    +
    void destroy_custom_filters()
+
    +
    +

    +
    +

    Custom operators

    +

    Another feature we’ve added is the possibility to create your own operators.

    +

    Like custom filters, custom operators need to be registered in order to be used:

    +
    void register_simple_custom_operator(const char* name, list* (*operator)(list* nodes));
+
    +
    +

    The first argument is the name of the operator. This name will be used to call the operator. You can call your operator with an exclamation point. For example, if we register the operator second we can call it with ”!second”.

    +

    The second argument is a pointer to a function that applies the operator. This function must be defined and provided by the user.

    +

    We already provide two custom operators that we call extended operators. They have the following mean:

    +
      +
    • first - Returns the first occurrence of an element. If you write “device!first” it will return the first device element.
      • +
    • text-children - Returns the text below an element. If you write “device!text-children” it will return all the text nodes directly below elements with tag device.

    However, in order to use them you need to call:

    +
    register_extended_operators()

    +

    and when you’re done you should call:
