I actually just changed the =~ to !~ and it works as expected with your regex. I don't understand from the OP what you want, and so I don't understand how the logical negation of Corion's regex gives you what you want. Can you elucidate, perhaps with some matching and non-matching example strings? Are you sure you're really matching what you think you're matching? (Please see perlre, perlretut, and perlrequick.)

Hm, I think I understand the problem. The OP's regex: `if($view_tag =~ m/[^A-Za-z0-9_\-\.]/) {` [download] actually has a negative character class (leading `^`), rather than a start-of-string anchor. So the OP had to negate the pattern. My guess is that the OP really meant: `if($view_tag =~ m/^[A-Za-z0-9_\-\.]/) {` [download] Update: fixed a typo: `s/or-string/of-string/`	[reply] [d/l] [select]

My guess is that the OP really meant ... My guess is that your guess is probably pretty good, but lirc201 is the only one who can clear this up and I doubt we'll hear much more from that quarter. I guess this is just another mystery to be filed in the big, empty drawer labeled X. :) Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]
