Re: negative regex without !~

if ($string !~ /asdfasdf/) { ... }

is equivalent to

if (! ($string =~ /asdfasdf/) ) { ... }

or 

unless ($string =~ /asdfasdf/) { ... }

If that doesn't suffice, a better problem description is required.

Update: Fixed precendence issue that merlyn correctly noted.

I shouldn't have to say this, but any code, unless otherwise stated, is untested

`if ($string !~ /asdfasdf/) { ... }` is equivalent to `if (! $string =~ /asdfasdf/) { ... }` Not really. The latter parses as `if ((! $string) =~ /asdfasdf/) {....}` That's why `not` was invented... because the precedence of "!" is often far too high for most operations. -- Randal L.
