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:

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

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

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

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

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

       •   "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 ...
           }

       To find the value of a specific node in the tree, use the "mxmlFindPath()" function:

           mxml_node_t *value = mxmlFindPath(tree, "path/to/*/foo/bar");

       The  "mxmlGetInteger()",  "mxmlGetOpaque()",  "mxmlGetReal()", and "mxmlGetText()" functions retrieve the
       value from a node:

           mxml_node_t *node;

           int intvalue = mxmlGetInteger(node);

           const char *opaquevalue = mxmlGetOpaque(node);

           double realvalue = mxmlGetReal(node);

           int whitespacevalue;
           const char *textvalue = mxmlGetText(node, &whitespacevalue);

       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 (
           mxml_entity_cb_t cb
       );

   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 (
           mxml_entity_cb_t cb
       );

   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.

   mxmlFindPath
       Find a node with the given path.

       mxml_node_t * mxmlFindPath (
           mxml_node_t *top,
           const char *path
       );

       The "path" is a slash-separated list of element names. The name "*" is considered a wildcard for  one  or
       more levels of elements.  For example, "foo/one/two", "bar/two/one", "*/one", and so forth.

       The  first child node of the found node is returned if the given node has children and the first child is
       a value node.

   mxmlGetCDATA
       Get the value for a CDATA node.

       const char * mxmlGetCDATA (
           mxml_node_t *node
       );

       NULL is returned if the node is not a CDATA element.

   mxmlGetCustom
       Get the value for a custom node.

       const void * mxmlGetCustom (
           mxml_node_t *node
       );

       NULL is returned if the node (or its first child) is not a custom value node.

   mxmlGetElement
       Get the name for an element node.

       const char * mxmlGetElement (
           mxml_node_t *node
       );

       NULL is returned if the node is not an element node.

   mxmlGetFirstChild
       Get the first child of an element node.

       mxml_node_t * mxmlGetFirstChild (
           mxml_node_t *node
       );

       NULL is returned if the node is not an element node or if the node has no children.

   mxmlGetInteger
       Get the integer value from the specified node or its first child.

       int  mxmlGetInteger (
           mxml_node_t *node
       );

       0 is returned if the node (or its first child) is not an integer value node.

   mxmlGetLastChild
       Get the last child of an element node.

       mxml_node_t * mxmlGetLastChild (
           mxml_node_t *node
       );

       NULL is returned if the node is not an element node or if the node has no children.

   mxmlGetNextSibling
       Return the node type...

       mxml_node_t * mxmlGetNextSibling (
           mxml_node_t *node
       );

   mxmlGetOpaque
       Get an opaque string value for a node or its first child.

       const char * mxmlGetOpaque (
           mxml_node_t *node
       );

       NULL is returned if the node (or its first child) is not an opaque value node.

   mxmlGetParent
       Get the parent node.

       mxml_node_t * mxmlGetParent (
           mxml_node_t *node
       );

       NULL is returned for a root node.

   mxmlGetPrevSibling
       Get the previous node for the current parent.

       mxml_node_t * mxmlGetPrevSibling (
           mxml_node_t *node
       );

       NULL is returned if this is the first child for the current parent.

   mxmlGetReal
       Get the real value for a node or its first child.

       double  mxmlGetReal (
           mxml_node_t *node
       );

       0.0 is returned if the node (or its first child) is not a real value node.

   mxmlGetRefCount
       Get the current reference (use) count for a node.

       int  mxmlGetRefCount (
           mxml_node_t *node
       );

       The initial reference count of new nodes is 1. Use the mxmlRetain and mxmlRelease functions to  increment
       and decrement a node's reference count.

   mxmlGetText
       Get the text value for a node or its first child.

       const char * mxmlGetText (
           mxml_node_t *node,
           int *whitespace
       );

       NULL  is  returned if the node (or its first child) is not a text node.  The "whitespace" argument can be
       NULL.

   mxmlGetType
       Get the node type.

       mxml_type_t  mxmlGetType (
           mxml_node_t *node
       );

       MXML_IGNORE is returned if "node" is NULL.

   mxmlGetUserData
       Get the user data pointer for a node.

       void * mxmlGetUserData (
           mxml_node_t *node
       );

   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().

   mxmlIndexGetCount
       Get the number of nodes in an index.

       int  mxmlIndexGetCount (
           mxml_index_t *ind
       );

   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

           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 (

   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

       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
       );

           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,

       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,

           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 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 (

           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.

           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.
