regex matching websites only with http without www

Question

I want to get all the websites from HTML code. The problem is that I have a regex which takes all the URLs but there needs to be www in the address. What kind of regex I need to use to get the URLs without www in the content?

update: The regex I am using is:

string anchorPattern = 
  @"(?<Protocol>\w+)://(?<Domain>[\w@][\w.:@]+)/?[\w.?=%&=\-@/$,&amp;+]*'";

@AdamMihalcin: As long as he just wants to extract URLs it's perfectly fine to use a regex. The fact that it's a HTML document doesn't really matter since he is not looking for urls inside e.g. href attributes. — ThiefMaster, May 17 '12 at 21:07

add (?=www) for only urls that have www

@"(?<Protocol>\w+)://(?=www)(?<Domain>[\w@][\w.:@]+)/?[\w.?=%&=\-@/$,&amp;+]*"

or add (?!www) for no www urls

@"(?<Protocol>\w+)://(?!www)(?<Domain>[\w@][\w.:@]+)/?[\w.?=%&=\-@/$,&amp;+]*"

One like you have, but without the part of the regex that looks like www\.
