<h2><a name="mxmlAdd">mxmlAdd()</a></h2>
<p>Add a node to a tree.
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.</p>

<h2><a name="mxmlFindElement">mxmlFindElement()</a></h2>
<p>Find the named element.
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.</p>

<h2><a name="mxmlLoadFile">mxmlLoadFile()</a></h2>
<p>Load a file into an XML node tree.
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 &lt;?xml&gt; 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.</p>
