Don't do that! Unless you enjoy poking yourself in the eye with a sharp stick and other such delightful activities, don't parse HTML using regexen. instead use HTML::TreeBuilder or one of the other HTML related modules - there are many.

I'd also strongly recommend that you always use strictures (use strict; use warnings;). my missing from the start of your sample lines indicates that either you don't, or that you are declaring your variables in too large a scope. It's that sharp stick thing again. ;)
