title: WPF C#, parse webbrowser content in htmlAgilityPack
body: <p>I need to scrap some data from a website, I create a webbrowser to allow the user to make login and use the search tool and once he searched and got the list with the results I want to have the ability to get this data and perform further analysis and have offline access.</p>
  
  <p>As I said the easiest approach for me is using a webbrowser, it works out of the box, login works, surfing works, and then when I reach the appropriated page I have the <code>webBrowser.Document</code> witch is a <code>mshtml.HTMLDocumentClass</code> (if I´m correct).
  But htmlAgilityPack request a <code>HtmlDocument</code></p>
  
  <p>What's the easiest way to parse from one to the other? Please notice the webbroser is WPF webbrowser.  </p>
