[Chicago-talk] Converting HEX to ASCII

[Andy_Bach at wiwb.uscourts.gov]

Hmm, not really all hex so (via perldoc -q decode):
$ echo '%#x3cIMG 
SRC=javascript:alert( 
'XSS')%#x3e
' | perl -pe 's/&#([[:xdigit:]]+);/chr $1/eg'
%#x3cIMG SRC=javascript:alert( 'XSS')%#x3e

if it were actually hex and not decimal ascii you'd add a call to "hex" in 
there:
' | perl -pe 's/&#([[:xdigit:]]+);/chr hex $1/eg'
