title: hpple elements within elements
body: <p>I have been using Hpple to parse some html in my iphone application (iOS5.1).  I have searched for all 'td' elements within a table row.  I am iterating through each of these elements, and for the most part I can retrieve all the information I need from the element, e.g.</p>
  
  <pre><code>[element objectForKey:@"rowspan"];
  </code></pre>
  
  <p>But one of the values I need is within the td:</p>
  
  <pre><code>&lt;tr&gt;
  &lt;td rowspan="3"&gt;  //This is my element
     &lt;div&gt;
        &lt;a&gt;link text&lt;/a&gt;  //The link text is what I want
     &lt;/div&gt;
  &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>Is there a way of getting the 'a' tags within my element, I have tried the following, but it doesn't work:</p>
  
  <pre><code>[[[element firstChild] firstChild] content];
  </code></pre>
  
  <p>Any help would be greatly appreciated!</p>
