URL read problem.	Can't Post

Hi,
I simply can't get this expression to work. It's suppose to take the hexdecimal values (eg: %3A) sent from a HTML <form> and translate it back into ASCII.

$Value =~ s/%(\dA-Fa-f)/pack("C", hex($1))/eg;

Any help would be greatly appreciated.

Thanks in advance, Matt.

You missed out the brackets to denote \dA-Fa-f should be interpreted as a character class (your code is trying to match a number followed by the string "A-Fa-f").

You probably wanted ...

s/%([\da-fA-F]{2})/pack("c",hex($1))/eg;

... instead.
