"And finally, running any regexp match overwrites the values of all the number variables (for instance, $2), so after checking $2 =~ /css/i, $2 will be undef."

Not true. Perl doesn't garuntee that it will overright those unless they actualy match. Since that regex isn't doing any captures he should be safe, not that I think its the best way to do it, but its safe.
