Well... Really, it doesn't work *at all*. You're not using an XML parser.
It's an HTML parser. Sure, it will do some kind of passable job of parsing
some kinds of XML, sort of, in some browsers.
Why not use a real XML parser?
function parseXML( xml ) {
if( window.ActiveXObject && window.GetObject ) {
var dom = new ActiveXObject( 'Microsoft.XMLDOM' );
dom.loadXML( xml );
return dom;
}
if( window.DOMParser )
return new DOMParser().parseFromString( xml, 'text/xml' );
throw new Error( 'No XML parser available' );
}
A quick test:
var dom = parseXML('<foo what="isit"><bar>howdy</bar></foo>');
var $dom = $(dom);
console.log( $dom.find('foo').attr('what') ); // "isit"
console.log( $dom.find('bar').text() ); // "howdy"
You could make it a plugin:
jQuery.parseXML = function( xml ) {
return jQuery( parseXML(xml) );
};
And then you can replace the first two lines of the test code above with:
var $dom = $.parseXML('<foo what="isit"><bar>howdy</bar></foo>');
