<td bgcolor="#eeeeff" class="text">Description: A generic XML parsing class that lets your set-up PHP functions
to be called when some XML elements are found. <br/>Using this class you can set handlers for specific XML paths,
for example /foo/data/name, for each handler you set up a PHP function in the form foo(attribs,name,content) {
print("<br/>");
print("Hey attribs);
print("<br/>");
}
parser->set_handler("/foo/data/name","name");
parser->set_handler("/foo/data/type/var","name");
if(!parser->get_error()."<br/>\n");
}
</pre>
<br/><br/>
As you can see using this class is very easy and can provide a lot of very good results. If the document
uses namespaces you can set-up paths based on local-names. (A handler setting paths using qualified names
is planned for a future release)
