  <p>I have got a URL like this:</p>
  
  <p><a href="http://somedomain.com/website/webpage.aspx?token=123456&amp;language=English" rel="nofollow noreferrer">http://somedomain.com/website/webpage.aspx?token=123456&amp;language=English</a></p>
  
  <p>My goal is to extract 123456 from it. There can only be one payment ID in the query-string parameter. What kind of regular expression can I use? I am using C# (.NET) by the way.</p>
  
  <p>Thanks</p>
