title: How to parse HTML from JavaScript in Firefox?
body: <p>What is the best way to parse (get a DOM tree of) a HTML result of XmlHttpRequest in Firefox?</p>
  
  <p>EDIT: </p>
  
  <p>I do <em>not</em> have the DOM tree, I want to acquire it.</p>
  
  <p>XmlHttpRequest's "responseXML" works only when the result is actual XML, so I have only responseText to work with.</p>
  
  <p><s>The innerHTML hack doesn't seem to work with a complete HTML document (in &lt;html>&lt;/html>).</s> - turns out it works fine.</p>
