[issue10539] Regular expression not checking 'range' element on 1st char in string.

[Eric Smith]

Eric Smith <eric at trueblade.com> added the comment:

I'm not sure I understand. The output I get is:

f42e6be1-29bf-4f3c-ba58-1ae1d9ca5f88
g42e6be1-29bf-4f3c-ba58-1ae1d9ca5f88
False

The first string matches. The second string matches because the leading "g" is being matched by "\w". The third string does not match because the "g" in the second position is not matched by "[0-9][a-f]".

For the second string you're matching "\w" followed by 7 "[0-9][a-f]", just as the regex allows.

Am I missing something?
