title: navigating dom in htmlagilitypack
body: <p>I am lost in HTML DOM. Using HTMLAgilityPack, how would I navigate the following nodes buried deep inside the DOM?</p>
  
  <pre><code>&lt;table&gt;
      &lt;tr&gt;
      &lt;td&gt; Name: &lt;/td&gt;
      &lt;td&gt; James &lt;/td&gt;
      &lt;/tr&gt;
  
      &lt;tr&gt;
      &lt;td&gt; age: &lt;/td&gt;
      &lt;td&gt; 33 &lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
