title: using a node to select a grandparent to select one of it's descendents
body: <p>I have a tree similar to this:</p>
  
  <pre><code>         tr
          _|_
         td  td
        _|    |_
       div     div
       _|       |_ 
   input       "foobar"
  </code></pre>
  
  <p>I have the node "foobar' selected using:</p>
  
  <pre><code>//*[normalize-space(text())='foobar']
  </code></pre>
  
  <p>But I am unable to select the great grandparent <code>tr</code> and select great grand child <code>input</code> with it. Any Suggestions?</p>
