title: How does HtmlNodeNavigator work?
body: <p>How to achieve </p>
  
  <pre><code>XPathDocument document = new XPathDocument("books.xml");
  XPathNavigator navigator = document.CreateNavigator();
  XPathNodeIterator nodeset = navigator.Select(xpath);
  
  while (nodeset.MoveNext())
  {
      // Clone iterator here when working with it.
      Do something
  }
  </code></pre>
  
  <p>in html agility pack? There is not much documentation. I have searched through the web. I can't get a piece of sample. There is no HtmlPathNodeIterator. HtmlNodeNavigator navigator = Html.CreateNavigator() doesn't work.</p>
  
  <p>Thanks in advance</p>
