title: Regexp to strip away wrapping DIV-tag
body: <p>In certain cases the response from the server is wrapped in a DIV-tag like this:</p>
  
  <pre><code>&lt;div id="marker-aab44ba9d64a41398ed97a251dfb938e-629"&gt;42&lt;/div&gt;
  </code></pre>
  
  <p>The content of the tag might be whatever: A string, a number, a URL, a javascript array, a javascript object. </p>
  
  <p>The format of the tag is always: </p>
  
  <pre><code>&lt;div id="marker-[random string here]"&gt;content&lt;/div&gt;
  </code></pre>
  
  <p><strong>I'd like to use regexp to strip away the tag.</strong> How do I do this?</p>
  
  <p>And remember: The response from the server might be just the content without the wrapping DIV, so the regexp should account for that. </p>
