title: jQuery :contains(regex)?
body: <p>Is it possible to have a jQuery selector where the :contains() is a regular expression?</p>
  
  <p>I need to select an element where the innerHTML contains something findable through regex?</p>
  
  <p>I know it's a short question. My apologies.</p>
  
  <pre><code>var t = $("#id a:containsRegex("/[0-9]/g")"); // Doesn't work
  </code></pre>
