I am trying to figure out the best way to determine if a string is a valid hex number. The way that popped in my head was: 
 
if ( $string =~ /[0-9a-fA-F]+/ ) {
   # valid number
} else {
   # not valid number
}

[download]

After reading input validation docs ( especially the ones concerning email address validation ) I get the feeling that there is probably a better way to do this. Any ideas?

Thanks
