  Hi,
  I am using the following function to match any URLS from within a string containing the html of a webpage:

  public List DumpHrefs(String inputString)
          {
              Regex r;
              Match m;
              List LstURLs = new List();
  
              r = new Regex("href\\s*=\\s*(?:\"(?<1>[^\"]*)\"|(?<1>\\S+))",
                  RegexOptions.IgnoreCase | RegexOptions.Compiled);
              for (m = r.Match(inputString); m.Success; m = m.NextMatch())
              {
                 LstURLs.Add(m.Groups[1].ToString());
              }
              return LstURLs;
          }
  

   

  However the problem with this, is it returns all links on the page, and I only wish to return fully qualified links such as http://www.domain.com/page.html and not relitive links.
  Does anyone know how I can modfy my regex to do so?
  Regards
