title: Can jQuery selectors be used with DOM mutation observers?
body: <p>HTML5 includes a concept of <a href="http://updates.html5rocks.com/2012/02/Detect-DOM-changes-with-Mutation-Observers" rel="noreferrer">"mutation observers"</a> to monitor changes to the browser's DOM.</p>
  
  <p>Your observer callback will be passed data which looks a lot like DOM tree snippets. I don't know if they are exactly this or how they work really.</p>
  
  <p>But when you are writing code to interact with a 3rd party site over which you have no control, say with a Greasemonkey script or Google Chrome user script, you have to inspect the tree of elements passed in to find which information is relevant to you.</p>
  
  <p>This is much simpler with selectors, just like working with any DOM, than walking the tree manually, especially for cross-browser code.</p>
  
  <p><strong>Is there a way to use jQuery selectors with the data passed to HTML5 mutation observer callbacks?</strong></p>
