title: regex to get value of inside a particular TD in HTML
body: <p>I need to fetch a particular element in HTML that has the following pattern:
  (C#)</p>
  
  <pre><code>&lt;td class="blah" ...........&gt;Some text blah: page x of xx&lt;br&gt;
  </code></pre>
  
  <p>I need to get the value of xx.</p>
  
  <p>The only thing that is constant in the above pattern is:</p>
  
  <ol>
  <li>its a TD element</li>
  <li>it has class="blah" in it</li>
  <li>it has the text pattern ": page x of xx<br></li>
  </ol>
  
  <p>You can assume there is only 1 occurance of the above pattern.</p>
