<h4 class="discussion">Discussion</h4>
<p class="discussion">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 &lt;?xml&gt; 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.<br>
<br>
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.<br>
<br>
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.
