title: Xpath to select next parent of the current node
body: <p>if tr contains <code>class="productnamecolor colors_productname"</code> i want to select next <code>tr</code> which contains the price details. so i use :</p>
  
  <pre><code>.//a[@class="productnamecolor colors_productname"]/parent::node()/following-sibling::tr
  </code></pre>
  
  <p>But didn't work. What is wrong with this expression?</p>
  
  <p>HTML :</p>
  
  <pre><code>&lt;tr&gt; 
   &lt;td valign="top" width="100%"&gt;
    &lt;a href="unclesamsretailoutlet.com/Trouser-Suspenders-8440015269920-p/…; class="productnamecolor colors_productname" title="Trouser Suspenders, 2323"&gt;Trouser Suspenders&lt;/a&gt; 
    &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>thanx in advance.</p>
