[jQuery] Parsing XML using jQuery

[Wallonman]

Hi,

Some hours that I don't understand why this basic Xml parsing with
JQuery doesn't work:

            $(document).ready(function() {

                var xml = '<?xml version="1.0" encoding="utf-8"?
><root><p>Hello World!</p></root>';

                alert($("p", xml).text());

            });

I get an empty string, instead of the expected Hello World!

I had a look to a similar previous post
http://groups.google.com/group/jquery-en/browse_thread/thread/fc60b77f884e6866/85cbd666774c6780)
, but this didn't help me to get the revelation.
