Driving license number format / regex pattern for European countries

I'm trying to create a regex pattern based validator for the Driving License numbers across various European countries (United Kingdom, Germany, France, Denmark, Holland, Italy, Ireland, Spain). Out of this list, on the web I could get some insight only into the UK DL format, but could not find any information on the patterns for the other countries' DLs. Can anyone provide any information about the Driving License number pattern for these countries?

By the way, this is where I got the pattern for UK (England, Scotland and Wales) DLs. Am looking for similar stuff for the other countries too.
