in reply to Script Stripper

@foo{ qw/a b c/ }++ on an empty %foo, will have $foo{a} be 1 and $foo{b} and $foo{c} be undef. That's no problem, because it's only being used for exists. You can have $foo{a} be undef too, by assigning an empty list to the hash splice: @foo{ qw/a b c/ } = ()

By the way, think about these:

<style> span.blah { background-color: expression(alert('Hello, World!' +)) } </style> <a href="javascript:alert('Hello, World!');">hi mom</a> <img src="fourohfour" onerror="alert('Hello, World!');">
It may be better to define what IS allowed, instead of what's NOT. HTML changes continuously, and browsers don't always follow specs...

For the quotes: just use HTML::Entities, and have it change double quotes to &quot;, zo you can safely use double quotes.

    Long live Perl 6.
    %hash{qw(a b c)} ^= 1; # or maybe... %hash{qw(a b c)}^++;

      Perl6 will indeed be great. But undef values are sufficient in this case ;)
