# Strip <script [..]>..</script> and <style>..</style> $content =~ s!<(s(?:cript|tyle))[^>]*>.*?</\1>!!gis;

    There are plenty of things that will be missed with your regex. For instance, all of the onclick/focus/load/etc events.

    Have a look at HTML::StripScripts::Parser, which allows you to customise the HTML / CSS that you would like to allow, while removing XSS attacks.
