Need Help??

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/

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]
