title: Go Through innerHTML to Find A Tag with Certain Class
body: <p>I'm curious as to what the DRYest approach to grabbing an A tag with a certain class is if the A tag is buried within the innerHTML of an element. The innerHTML contains all sorts of divs and other A tags if that's necessary to know. Below is an example of what I'm talking about:</p>
  
  <pre><code>var content = something[0].innerHTML;
  // I would want to see whether an A tag with say a certain class "button" exists within "content" then store that A tag in another variable.
  </code></pre>
