AJAX response to DOM traversing problem

AJAX response to DOM traversing problem

Hey guys,

I'm trying to do an AJAX call and convert the response (which is a HTML document) into DOM, so I can traverse it via .find()
I've successfully done it before using jQuery 1.2.6, but the following example code doesn't seem to work in 1.4.1 for me anymore:
  1. alert($('<div class="message_confirm"><p>Hello</p></div>').find('div.message_confirm').html());
That piece of code, IMHO, should come up with a "<p>Hello</p>" message, am I correct?
However, instead, it comes up with "null".

Anyone can spot a problem there?
