Honestly, I'm not very good with regular expressions -- and try to avoid them when possible. But in cases where they seem to be the best option, I have formed a heavy dependence on regex debuggers like kodos. http://kodos.sourceforge.net/ > Anyways, any suggestions to fix the below code? <snip> Have you had a look at the python-ldap package? http://python-ldap.sourceforge.net/ You could probably access ldap directly with python, if that's an option. Or, you could roll your own ldif parser (but make sure your data contains a newline between each dn, or the parser will choke with a 'ValueError: Two lines starting with dn: in one record.'): import ldif from cStringIO import StringIO class MyLDIF(ldif.LDIFParser): def __init__(self, inputfile): ldif.LDIFParser.__init__(self, inputfile) self.users = [] def handle(self, dn, entry): self.users.append((entry['uid'], entry['cn'])) raw = """\ <snip your ldif example with newlines added between dns> """ if __name__ == '__main__': io = StringIO(raw) lp = MyLDIF(io) lp.parse() for user in lp.users: uid = user[0][0] cn = user[1][0] print uid print cn ... or ... You could also use ldif.LDIFRecordList directly without creating a custom parser class which would return a list of (dn, entry) tuples. The module author warns that 'It can be a memory hog!', and I can imagine this is true if you are working with a particularly large ldap directory. io = StringIO(raw) directory = ldif.LDIFRecordList(io) directory.parse() for dn, entry in directory.all_records: print entry['uid'][0] print entry['cn'][0] _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
