What is the best way to parse (get a DOM tree of) a HTML result of XmlHttpRequest in Firefox?

EDIT:

I do not have the DOM tree, I want to acquire it.

XmlHttpRequest's responseXML works only when the result is actual XML, so I have only responseText to work with.

~~The innerHTML hack doesn't seem to work with a complete HTML document (in <html></html>).~~ - turns out it works fine.

innerHTML should work just fine, e.g.

// This would be after the Ajax request:

var myHTML = XHR.responseText;

var tempDiv = document.createElement('div');

tempDiv.innerHTML = myHTML.replace(/<script(.|s)*?/script>/g, '');



// tempDiv now has a DOM structure:

tempDiv.childNodes;

tempDiv.getElementsByTagName('a'); // etc. etc.
