<H4>Description</H4>
|
|
<P>Load a file descriptor into an XML node tree using a SAX callback.</P>
|
|
<P>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.</P>
|
|
<P>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>
|
|
<P>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.</P>
