Hello,
I'm trying to get working an assertion which filter address from some domain
but if it's prefixed by '.com'.
Even trying to put the result in a negate test I can't get the wanted result.
The tought in program term :
>>> def filter(adr):
... import re
... allow = re.compile('.*\.my(>|$)')
... deny = re.compile('.*\.com\.my(>|$)')
... cnt = 0
... if deny.search(adr): cnt += 1
... if allow.search(adr): cnt += 1
... return cnt
...
>>> filter('[EMAIL PROTECTED]')
2
>>> filter('[EMAIL PROTECTED]')
1
>>>
Seem that I miss some better regex implementation to avoid that both of the
filters taking action. I'm thinking of lookbehind (negative or positive)
option, but I think I couldn't realize it yet.
I think the compilation should either allow have no '.com' before '.my' or
deny should have _only_ '.com' before '.my'. Sorry I don't get the correct
sintax to do it.
Suggestions are welcome.
