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
);

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.

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.

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.

const char * mxmlGetOpaque (
mxml_node_t *node
);
NULL is returned if the node (or its first child) is not an opaque value 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.

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 (

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.

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.
