Ah, so you do want to anchor at the beginning and end of the string. Have you looked at perlrequick (http://perldoc.perl.org/perlrequick.html) as Uri suggested? That should show you how to anchor a regex to the start and end of a string. Post what you're trying after looking there. Regards, Tim Bowden BTW, please try not to top post.
