I'm sorry, that regex wasn't meant to be taken literally.

Your \b anchors aren't effective on the *entire* pattern. You're matching \bI(?:I+|V|X)? or VI* or XI*\b The regex I would use would probably be /\b(?:I{1,3}|IV|VI{0,3}|I?X)\b/ -- Jeff "japhy" Pinyan % How can we ever be the sold short or RPI Acacia Brother #734 % the cheated, we who for every service http://japhy.perlmonk.org/ % have long ago been overpaid? http://www.perlmonks.org/ % -- Meister Eckhart -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response> -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
