pattern for even number of HEX digits using Nick Gammon's Regexp library

RayL:
I'm sorry, but I still can't find where in the code I provided thus far you're able to find the "; " you mention.
Could you give me the Reply # and perhaps what the line begins with. From there I should be able to locate the line of code.

Either I am going mad or someone is editing your code after posting it. This time I most definitely did see a space following a ';' .

The limitations of this regex library make it almost impossible for me to help any further.
