title: How to get a certain part of current URL in silverlight?
body: <p>I need a certain part of current URL. <br>
  Say for example the URL is: <a href="http://www.abc.com/123/product/234?productid=123" rel="nofollow noreferrer">http://www.abc.com/123/product/234?productid=123</a> <br>
  And I want to check if a certain string contains <a href="http://www.abc.com/123" rel="nofollow noreferrer">http://www.abc.com/123</a></p>
  
  <p>Please don't give answers like "do string manipulation" and all. 
  Is there a way to get this sort of URL?</p>
