I've sent this personally in order to avoid flooding the list with responses. If this wasn't your intention, please bounce it back to the list.

There are at least 10 other ways of doing it, some probably more efficient and shorter. I just came up with this at the top of my head. > 3. how easy is it for you to write such a regexp? Piece of cake. But then again I'm fluent in Perl and that comes as a bonus. > 4. if you can't write it, would it be hard to learn, do you think? About as hard as looking up a good piece of documentation like perlre(1). > 5. can you estimate how easy/hard it is for other people? The lay user designing John Q. Public's Homepage? Impossible. The advanced computer user could learn it in a minute. -- Stephanos Piperoglou -- sp249@cam.ac.uk ------------------- All I want is a little love and a lot of money.
