Crawl through all links

As I am still working on a migration project, the customer asked me if it was possible to check all urls in content editor webparts that I migrated. As i serialized all webparts on a 2003 to xml (for importing them to 2007), it was very easy for me to locate all content editor webparts, scan it's content and report the external, non-existant urls in it and change/report the internal, non-existant url's.

<br />public static void GetAllUrls(string content)<br />{<br /> string pattern = @"\b([\d\w\.\/\+\-\?\:]*)((ht|f)tp(s|)\:\/\/|[\d\d\d|\d\d]\.[\d\d\d|\d\d]\.|www\.|\.tv|\.ac|\.com|\.edu|\.gov|\.int|\.mil|\.net|\.org|\.biz|\.info|\.name|\.pro|\.museum|\.co)([\d\w\.\/\%\+\-\=\&\?\:\\\"\'\,\|\~\;]*)\b";<br /><br /><br /> //Set up regex object <br /> Regex RegExpr = new Regex(pattern, RegexOptions.IgnoreCase);<br /><br /> //get the first match <br /> Match match = RegExpr.Match(content);<br /><br /> //loop through matches <br /><br /> Console.WriteLine(content);<br /> while (match.Success)<br /> {<br /><br /> //output the match info <br /> Console.WriteLinematch.Groups[0].Value); <br /> Console.WriteLinematch.Groups[1].Value); <br /> <br />//get next match <br /> match = match.NextMatch();<br /> } <br />
