As German nouns have to be "capitalized" words, I can't use this regex.

That's better! Here's my latest regex:

reg = re.compile(r"\b[%s]\w+-?(?:,\s\b[%s]\w+)*\sund\s\b[%s]\w+"
                 
%(string.uppercase,string.uppercase,string.uppercase),re.UNICODE)


It works (matches also "Berlin, London,Wien  und Paris"),
but I don't like it because of  
%(string.uppercase,string.uppercase,string.uppercase).
The former version looks better:

reg3 = re.compile(r"(?:[%s\w-]+(?:,|\sund)?\s)+"
                  %(string.uppercase),
                  re.UNICODE)

Unfortunately, it finds pretty more things than I wanted it to find.


Many greetings,
