If a regex works with sed then it will work with witango as they use the same library.
If you want to use regex in your apps get a hold of the book Mastering Regular Expressions (If your an insomniac it is an excellent drug free cure).

Regextastic!
From the story, "The pseudo-BNF is pretty straightforward..."
Yes, the 2+ page context free grammar that this monstrous regex represents is indeed straightforward.
Bwahahahahahahaha!

You can read the story of it at http://www.foad.org/~abigail/Perl/url2.html.
I haven't tested it, because I think it's pathological enough to get posted as is!
J.
Think this came up once before. Worth a look through the archives.
The challenge is to find the string that represents an URL, which begins with http:// and ends with the first space after that.
Tricky.
