Buckaroo Buddha has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to replace the HTML escape codes from the GET string.

as you may well know, special characters
get turned into their hexadecimal name
eg: , would become %2C
   % would become %25


i need to make sure i do it for every occurance of a percent sign

can anyone help me write the regex for that?
