Regex for splitting a german address into its parts

Question

Good evening,

I\'m trying to splitting the parts of a german address string into its parts via Java. Does anyone know a regex or a library to do this? To split it like t

Answer 1

At first glance it looks like a simple whitespace would do it, however looking closer I notice the address always has 4 parts, and the first part can have whitespace.

What I would do is something like this (psudeocode):

address[4] = empty
split[?] = address_string.split(" ")
address[3] = split[last]
address[2] = split[last - 1]
address[1] = split[last - 2]
address[0] = join split[first] through split[last - 3] with whitespace, trim trailing whitespace with trim()

However, this will only handle one form of address. If addresses are written multiple ways it could be much more tricky.
