NAME
       mxml - Mini-XML API

INCLUDE FILE
       #include <mxml.h>

LIBRARY
       -lmxml

DESCRIPTION
       Mini-XML is a small XML parsing library that you can use to read XML
       and XML-like data files in your application without requiring large
       non-standard libraries.  Mini-XML only requires an ANSI C compatible
       compiler (GCC works, as do most vendors' ANSI C compilers) and a "make"
       program.

       Mini-XML provides the following functionality:

       o   Reading of UTF-8 and UTF-16 and writing of UTF-8 encoded XML files
           and strings.

       o   Data is stored in a linked-list tree structure, preserving the XML
           data hierarchy.

       o   Supports arbitrary element names, attributes, and attribute values
           with no preset limits, just available memory.

       o   Supports integer, real, opaque ("cdata"), and text data types in
           "leaf" nodes.

       o   Functions for creating, indexing, and managing trees of data.

       o   "Find" and "walk" functions for easily locating and navigating
           trees of data.

       Mini-XML doesn't do validation or other types of processing on the data
       based upon schema files or other sources of definition information, nor
       does it support character entities other than those required by the XML
       specification.

USING MINI-XML
       Mini-XML provides a single header file which you include:

           #include <mxml.h>

       Nodes are defined by the "mxml_node_t" structure; the "type" member
       defines the node type (element, integer, opaque, real, or text) which
       determines which value you want to look at in the "value" union.  New
       nodes can be created using the "mxmlNewElement()", "mxmlNewInteger()",
       "mxmlNewOpaque()", "mxmlNewReal()", and "mxmlNewText()" functions.
       Only elements can have child nodes, and the top node must be an
       element, usually "?xml".

       You load an XML file using the "mxmlLoadFile()" function:

           FILE *fp;
           mxml_node_t *tree;

           fp = fopen("filename.xml", "r");
           tree = mxmlLoadFile(NULL, fp, MXML_NO_CALLBACK);
           fclose(fp);

       Similarly, you save an XML file using the "mxmlSaveFile()" function:

           FILE *fp;
           mxml_node_t *tree;

           fp = fopen("filename.xml", "w");
           mxmlSaveFile(tree, fp, MXML_NO_CALLBACK);
           fclose(fp);

       The "mxmlLoadString()", "mxmlSaveAllocString()", and "mxmlSaveString()"
       functions load XML node trees from and save XML node trees to strings:

           char buffer[8192];
           char *ptr;
           mxml_node_t *tree;

           ...
           tree = mxmlLoadString(NULL, buffer, MXML_NO_CALLBACK);

           ...
           mxmlSaveString(tree, buffer, sizeof(buffer),
                          MXML_NO_CALLBACK);

           ...
           ptr = mxmlSaveAllocString(tree, MXML_NO_CALLBACK);

       You can find a named element/node using the "mxmlFindElement()"
       function:

           mxml_node_t *node = mxmlFindElement(tree, tree, "name",
                                               "attr", "value",
                                               MXML_DESCEND);

       The "name", "attr", and "value" arguments can be passed as NULL to act
       as wildcards, e.g.:

           /* Find the first "a" element */
           node = mxmlFindElement(tree, tree, "a", NULL, NULL,
                                  MXML_DESCEND);

           /* Find the first "a" element with "href" attribute */
           node = mxmlFindElement(tree, tree, "a", "href", NULL,
                                  MXML_DESCEND);

           /* Find the first "a" element with "href" to a URL */
           node = mxmlFindElement(tree, tree, "a", "href",
                                  "http://www.easysw.com/~mike/mxml/",
                                  MXML_DESCEND);

           /* Find the first element with a "src" attribute*/
           node = mxmlFindElement(tree, tree, NULL, "src", NULL,
                                  MXML_DESCEND);

           /* Find the first element with a "src" = "foo.jpg" */
           node = mxmlFindElement(tree, tree, NULL, "src",
                                  "foo.jpg", MXML_DESCEND);

       You can also iterate with the same function:

           mxml_node_t *node;

           for (node = mxmlFindElement(tree, tree, "name", NULL,
                                       NULL, MXML_DESCEND);
                node != NULL;
                node = mxmlFindElement(node, tree, "name", NULL,
                                       NULL, MXML_DESCEND))
           {
             ... do something ...
           }

       Finally, once you are done with the XML data, use the "mxmlDelete()"
       function to recursively free the memory that is used for a particular
       node or the entire tree:

           mxmlDelete(tree);

FUNCTIONS
   mxmlAdd
       Add a node to a tree.

       void mxmlAdd (
           mxml_node_t *parent,
           int where,
           mxml_node_t *child,
           mxml_node_t *node
       );

       Adds the specified node to the parent. If the child argument is not
       NULL, puts the new node before or after the specified child depending
       on the value of the where argument. If the child argument is NULL, puts
       the new node at the beginning of the child list (MXML_ADD_BEFORE) or at
       the end of the child list (MXML_ADD_AFTER). The constant
       MXML_ADD_TO_PARENT can be used to specify a NULL child pointer.

   mxmlDelete
       Delete a node and all of its children.

       void mxmlDelete (
           mxml_node_t *node
       );

       If the specified node has a parent, this function first removes the
       node from its parent using the mxmlRemove() function.

   mxmlElementDeleteAttr
       Delete an attribute.

       void mxmlElementDeleteAttr (
           mxml_node_t *node,
           const char *name
       );

   mxmlElementGetAttr
       Get an attribute.

       const char * mxmlElementGetAttr (
           mxml_node_t *node,
           const char *name
       );

       This function returns NULL if the node is not an element or the named
       attribute does not exist.

   mxmlElementSetAttr
       Set an attribute.

       void mxmlElementSetAttr (
           mxml_node_t *node,
           const char *name,
           const char *value
       );

       If the named attribute already exists, the value of the attribute is
       replaced by the new string value. The string value is copied into the
       element node. This function does nothing if the node is not an element.

   mxmlElementSetAttrf
       Set an attribute with a formatted value.

       void mxmlElementSetAttrf (
           mxml_node_t *node,
           const char *name,
           const char *format,
           ...
       );

       If the named attribute already exists, the value of the attribute is
       replaced by the new formatted string. The formatted string value is
       copied into the element node. This function does nothing if the node is
       not an element.



   mxmlEntityAddCallback
       Add a callback to convert entities to Unicode.

       int  mxmlEntityAddCallback (void);

   mxmlEntityGetName
       Get the name that corresponds to the character value.

       const char * mxmlEntityGetName (
           int val
       );

       If val does not need to be represented by a named entity, NULL is
       returned.

   mxmlEntityGetValue
       Get the character corresponding to a named entity.

       int  mxmlEntityGetValue (
           const char *name
       );

       The entity name can also be a numeric constant. -1 is returned if the
       name is not known.

   mxmlEntityRemoveCallback
       Remove a callback.

       void mxmlEntityRemoveCallback (void);

   mxmlFindElement
       Find the named element.

       mxml_node_t * mxmlFindElement (
           mxml_node_t *node,
           mxml_node_t *top,
           const char *name,
           const char *attr,
           const char *value,
           int descend
       );

       The search is constrained by the name, attribute name, and value; any
       NULL names or values are treated as wildcards, so different kinds of
       searches can be implemented by looking for all elements of a given name
       or all elements with a specific attribute. The descend argument
       determines whether the search descends into child nodes; normally you
       will use MXML_DESCEND_FIRST for the initial search and MXML_NO_DESCEND
       to find additional direct descendents of the node. The top node
       argument constrains the search to a particular node's children.

   mxmlIndexDelete
       Delete an index.

       void mxmlIndexDelete (
           mxml_index_t *ind
       );

   mxmlIndexEnum
       Return the next node in the index.

       mxml_node_t * mxmlIndexEnum (
           mxml_index_t *ind
       );

       Nodes are returned in the sorted order of the index.

   mxmlIndexFind
       Find the next matching node.

       mxml_node_t * mxmlIndexFind (
           mxml_index_t *ind,
           const char *element,
           const char *value
       );

       You should call mxmlIndexReset() prior to using this function for the
       first time with a particular set of "element" and "value" strings.
       Passing NULL for both "element" and "value" is equivalent to calling
       mxmlIndexEnum().

   mxmlIndexNew
       Create a new index.

       mxml_index_t * mxmlIndexNew (
           mxml_node_t *node,
           const char *element,
           const char *attr
       );

       The index will contain all nodes that contain the named element and/or
       attribute. If both "element" and "attr" are NULL, then the index will
       contain a sorted list of the elements in the node tree.  Nodes are
       sorted by element name and optionally by attribute value if the "attr"
       argument is not NULL.

   mxmlIndexReset
       Reset the enumeration/find pointer in the index and return the first
       node in the index.

       mxml_node_t * mxmlIndexReset (
           mxml_index_t *ind
       );

       This function should be called prior to using mxmlIndexEnum() or
       mxmlIndexFind() for the first time.

   mxmlLoadFd
       Load a file descriptor into an XML node tree.

       mxml_node_t * mxmlLoadFd (
           mxml_node_t *top,
           int fd,
           mxml_load_cb_t cb
       );

       The nodes in the specified file are added to the specified top node.
       If no top node is provided, the XML file MUST be well-formed with a
       single parent node like <?xml> for the entire file. The callback
       function returns the value type that should be used for child nodes.
       If MXML_NO_CALLBACK is specified then all child nodes will be either
       MXML_ELEMENT or MXML_TEXT nodes.

       The constants MXML_INTEGER_CALLBACK, MXML_OPAQUE_CALLBACK,
       MXML_REAL_CALLBACK, and MXML_TEXT_CALLBACK are defined for loading
       child nodes of the specified type.

   mxmlLoadFile
       Load a file into an XML node tree.

       mxml_node_t * mxmlLoadFile (
           mxml_node_t *top,
           FILE *fp,
           mxml_load_cb_t cb
       );

       The nodes in the specified file are added to the specified top node.
       If no top node is provided, the XML file MUST be well-formed with a
       single parent node like <?xml> for the entire file. The callback
       function returns the value type that should be used for child nodes.
       If MXML_NO_CALLBACK is specified then all child nodes will be either
       MXML_ELEMENT or MXML_TEXT nodes.

       The constants MXML_INTEGER_CALLBACK, MXML_OPAQUE_CALLBACK,
       MXML_REAL_CALLBACK, and MXML_TEXT_CALLBACK are defined for loading
       child nodes of the specified type.

   mxmlLoadString
       Load a string into an XML node tree.

       mxml_node_t * mxmlLoadString (
           mxml_node_t *top,
           const char *s,
           mxml_load_cb_t cb
       );

       The nodes in the specified string are added to the specified top node.
       If no top node is provided, the XML string MUST be well-formed with a
       single parent node like <?xml> for the entire string. The callback
       function returns the value type that should be used for child nodes.
       If MXML_NO_CALLBACK is specified then all child nodes will be either
       MXML_ELEMENT or MXML_TEXT nodes.

       The constants MXML_INTEGER_CALLBACK, MXML_OPAQUE_CALLBACK,
       MXML_REAL_CALLBACK, and MXML_TEXT_CALLBACK are defined for loading
       child nodes of the specified type.

   mxmlNewCDATA
       Create a new CDATA node.

       mxml_node_t * mxmlNewCDATA (
           mxml_node_t *parent,
           const char *data
       );

       The new CDATA node is added to the end of the specified parent's child
       list. The constant MXML_NO_PARENT can be used to specify that the new
       CDATA node has no parent. The data string must be nul-terminated and is
       copied into the new node. CDATA nodes use the MXML_ELEMENT type.



   mxmlNewCustom
       Create a new custom data node.

       mxml_node_t * mxmlNewCustom (
           mxml_node_t *parent,
           void *data,
           mxml_custom_destroy_cb_t destroy
       );

       The new custom node is added to the end of the specified parent's child
       list. The constant MXML_NO_PARENT can be used to specify that the new
       element node has no parent. NULL can be passed when the data in the
       node is not dynamically allocated or is separately managed.



   mxmlNewElement
       Create a new element node.

       mxml_node_t * mxmlNewElement (
           mxml_node_t *parent,

       mxml_node_t * mxmlNewInteger (
           mxml_node_t *parent,
           int integer
       );

       The new integer node is added to the end of the specified parent's
       child list. The constant MXML_NO_PARENT can be used to specify that the
       new integer node has no parent.

   mxmlNewOpaque
       Create a new opaque string.

       mxml_node_t * mxmlNewOpaque (
           mxml_node_t *parent,
           const char *opaque
       );

       The new opaque node is added to the end of the specified parent's child
       list. The constant MXML_NO_PARENT can be used to specify that the new
       opaque node has no parent. The opaque string must be nul-terminated and
       is copied into the new node.

   mxmlNewReal
       Create a new real number node.

       mxml_node_t * mxmlNewReal (
           mxml_node_t *parent,
           double real
       );

       The new real number node is added to the end of the specified parent's

       new real number node has no parent.

   mxmlNewText
       Create a new text fragment node.

       mxml_node_t * mxmlNewText (
           mxml_node_t *parent,
           int whitespace,
           const char *string
       );

       The new text node is added to the end of the specified parent's child
       list. The constant MXML_NO_PARENT can be used to specify that the new
       text node has no parent. The whitespace parameter is used to specify
       whether leading whitespace is present before the node. The text string
       must be nul-terminated and is copied into the new node.

   mxmlNewTextf
       Create a new formatted text fragment node.

       mxml_node_t * mxmlNewTextf (
           mxml_node_t *parent,
           int whitespace,
           const char *format,
           ...
       );

       The new text node is added to the end of the specified parent's child
       list. The constant MXML_NO_PARENT can be used to specify that the new
       text node has no parent. The whitespace parameter is used to specify
       whether leading whitespace is present before the node. The format
       string must be nul-terminated and is formatted into the new node.

       Create a new XML document tree.

       mxml_node_t * mxmlNewXML (
           const char *version
       );

       The "version" argument specifies the version number to put in the ?xml
       element node. If NULL, version 1.0 is assumed.



   mxmlRelease
       Release a node.

       int  mxmlRelease (
           mxml_node_t *node
       );

       When the reference count reaches zero, the node (and any children) is
       deleted via mxmlDelete().



   mxmlRemove
       Remove a node from its parent.

       void mxmlRemove (
           mxml_node_t *node
       );

       Does not free memory used by the node - use mxmlDelete() for that.
       This function does nothing if the node has no parent.

   mxmlRetain
       Retain a node.

       int  mxmlRetain (
           mxml_node_t *node
       );

   mxmlSAXLoadFd
       Load a file descriptor into an XML node tree using a SAX callback.

       mxml_node_t * mxmlSAXLoadFd (
           mxml_node_t *top,
           int fd,
           mxml_load_cb_t cb,
           mxml_sax_cb_t sax_cb,
           void *sax_data
       );

       The nodes in the specified file are added to the specified top node.
       If no top node is provided, the XML file MUST be well-formed with a
       single parent node like <?xml> for the entire file. The callback
       function returns the value type that should be used for child nodes.
       If MXML_NO_CALLBACK is specified then all child nodes will be either
       MXML_ELEMENT or MXML_TEXT nodes.

       The constants MXML_INTEGER_CALLBACK, MXML_OPAQUE_CALLBACK,
       MXML_REAL_CALLBACK, and MXML_TEXT_CALLBACK are defined for loading
       child nodes of the specified type.

       The SAX callback must call mxmlRetain() for any nodes that need to be
       kept for later use. Otherwise, nodes are deleted when the parent node
       is closed or after each data, comment, CDATA, or directive node.



   mxmlSAXLoadFile
       Load a file into an XML node tree using a SAX callback.

       mxml_node_t * mxmlSAXLoadFile (
           mxml_node_t *top,
           FILE *fp,
           mxml_load_cb_t cb,
           mxml_sax_cb_t sax_cb,
           void *sax_data
       );

       The nodes in the specified file are added to the specified top node.
       If no top node is provided, the XML file MUST be well-formed with a
       single parent node like <?xml> for the entire file. The callback
       function returns the value type that should be used for child nodes.
       If MXML_NO_CALLBACK is specified then all child nodes will be either
       MXML_ELEMENT or MXML_TEXT nodes.

       The constants MXML_INTEGER_CALLBACK, MXML_OPAQUE_CALLBACK,
       MXML_REAL_CALLBACK, and MXML_TEXT_CALLBACK are defined for loading
       child nodes of the specified type.

       The SAX callback must call mxmlRetain() for any nodes that need to be
       kept for later use. Otherwise, nodes are deleted when the parent node
       is closed or after each data, comment, CDATA, or directive node.



   mxmlSAXLoadString
       Load a string into an XML node tree using a SAX callback.

       mxml_node_t * mxmlSAXLoadString (
           mxml_node_t *top,
           const char *s,
           mxml_load_cb_t cb,
           mxml_sax_cb_t sax_cb,
           void *sax_data
       );

       The nodes in the specified string are added to the specified top node.
       If no top node is provided, the XML string MUST be well-formed with a
       single parent node like <?xml> for the entire string. The callback
       function returns the value type that should be used for child nodes.
       If MXML_NO_CALLBACK is specified then all child nodes will be either
       MXML_ELEMENT or MXML_TEXT nodes.

       The constants MXML_INTEGER_CALLBACK, MXML_OPAQUE_CALLBACK,
       MXML_REAL_CALLBACK, and MXML_TEXT_CALLBACK are defined for loading
       child nodes of the specified type.

       The SAX callback must call mxmlRetain() for any nodes that need to be
       kept for later use. Otherwise, nodes are deleted when the parent node
       is closed or after each data, comment, CDATA, or directive node.



   mxmlSaveAllocString
       Save an XML node tree to an allocated string.

       char * mxmlSaveAllocString (
           mxml_node_t *node,
           mxml_save_cb_t cb
       );

       This function returns a pointer to a string containing the textual
       representation of the XML node tree.  The string should be freed using
       the free() function when you are done with it.  NULL is returned if the
       node would produce an empty string or if the string cannot be
       allocated.

       The callback argument specifies a function that returns a whitespace
       string or NULL before and after each element. If MXML_NO_CALLBACK is
       specified, whitespace will only be added before MXML_TEXT nodes with
       leading whitespace and before attribute names inside opening element
       tags.

   mxmlSaveFd
       Save an XML tree to a file descriptor.

       int  mxmlSaveFd (
           mxml_node_t *node,
           int fd,
           mxml_save_cb_t cb
       );

       The callback argument specifies a function that returns a whitespace
       string or NULL before and after each element. If MXML_NO_CALLBACK is
       specified, whitespace will only be added before MXML_TEXT nodes with
       leading whitespace and before attribute names inside opening element
       tags.

   mxmlSaveFile
       Save an XML tree to a file.

       int  mxmlSaveFile (
           mxml_node_t *node,
           FILE *fp,
           mxml_save_cb_t cb
       );

       The callback argument specifies a function that returns a whitespace
       string or NULL before and after each element. If MXML_NO_CALLBACK is
       specified, whitespace will only be added before MXML_TEXT nodes with
       leading whitespace and before attribute names inside opening element
       tags.

   mxmlSaveString
       Save an XML node tree to a string.

       int  mxmlSaveString (
           mxml_node_t *node,
           char *buffer,
           int bufsize,
           mxml_save_cb_t cb
       );

       This function returns the total number of bytes that would be required
       for the string but only copies (bufsize - 1) characters into the
       specified buffer.

       The callback argument specifies a function that returns a whitespace
       string or NULL before and after each element. If MXML_NO_CALLBACK is
       specified, whitespace will only be added before MXML_TEXT nodes with
       leading whitespace and before attribute names inside opening element
       tags.

   mxmlSetCDATA
       Set the element name of a CDATA node.

       int  mxmlSetCDATA (
           mxml_node_t *node,
           const char *data
       );

       The node is not changed if it is not a CDATA element node.



   mxmlSetCustom
       Set the data and destructor of a custom data node.

       int  mxmlSetCustom (
           mxml_node_t *node,
           void *data,
           mxml_custom_destroy_cb_t destroy
       );

           mxml_custom_load_cb_t load,
           mxml_custom_save_cb_t save
       );

       The load function accepts a node pointer and a data string and must
       return 0 on success and non-zero on error.

       The save function accepts a node pointer and must return a malloc'd
       string on success and NULL on error.

   mxmlSetElement
       Set the name of an element node.

       int  mxmlSetElement (
           mxml_node_t *node,
           const char *name
       );

       The node is not changed if it is not an element node.

       int  mxmlSetOpaque (
           mxml_node_t *node,
           const char *opaque
       );

       The node is not changed if it is not an opaque node.

       Set the value of a real number node.

       int  mxmlSetReal (
           mxml_node_t *node,
           double real
       );

       The node is not changed if it is not a real number node.

   mxmlSetText
       Set the value of a text node.

       int  mxmlSetText (
           mxml_node_t *node,
           int whitespace,
           const char *string
       );

       The node is not changed if it is not a text node.

   mxmlSetTextf
       Set the value of a text node to a formatted string.

       int  mxmlSetTextf (
           mxml_node_t *node,
           int whitespace,
           const char *format,
           ...
       );

       The node is not changed if it is not a text node.

   mxmlSetWrapMargin
       Set the the wrap margin when saving XML data.

       void mxmlSetWrapMargin (
           int column
       );

       Wrapping is disabled when "column" is <= 0.



   mxmlWalkNext
       Walk to the next logical node in the tree.

       mxml_node_t * mxmlWalkNext (
           mxml_node_t *node,
           mxml_node_t *top,
           int descend
       );

       The descend argument controls whether the first child is considered to
       be the next node. The top node argument constrains the walk to the
       node's children.

   mxmlWalkPrev
       Walk to the previous logical node in the tree.

       mxml_node_t * mxmlWalkPrev (
           mxml_node_t *node,
           mxml_node_t *top,
           int descend
       );

       The descend argument controls whether the previous node's last child is
