Separate the house number from the street name

Separate the house number from the street name is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

In Germany and the Netherlands has a postal address the form street name followed by the house number in accordance with the national standards DIN 5008 respectively NEN 5825. The problem is that some street names has numbers e.g. special years and some [house numbers] has characters as an extension.

Task

Develop a program which separates the house number form the street name and represents them both. A test-set:

Plataanstraat 5
Straat 12
Straat 12 II
Dr. J. Straat   12
Dr. J. Straat 12 a
Dr. J. Straat 12-14

Plein 1940 2
1213-laan 11
16 april 1944 Pad 1
1e Kruisweg 36
Laan 1940-’45 66
Laan ’40-’45
Langeloërduinen 3 46

So, since I don't read German or Dutch, pending more explicit rules, I'm going to assume the number starts at the first decimal digit in the string and continues to the end, and that everything preceding that point is considered the street name.
