Hi
I want to test a string for three properties:
1) It is exactly 9 characters long.
2) Character number 5 is a comma (',').
3) The other characters are either numbers 0-9 or letters a-f.

I have been able to do this by a combination of strings methods for 1)
and 2), and using a regex match on the string (stripped of the comma)
with the following code:
myString =~ /([^a-f0-9])/

If possible I would like to simplify this by using a more advanced regex
match to check all three properties at one time. If this is possible,
perhaps one of you regex wizards out there could show me how? :)

Best regards,
Chris
