Your match could be done a number of ways, [A-Z]{2}[0-9]{2} or if Cocoon spits at this, try [A-Z][A-Z][0-9][0-9]
Any site dedicated to Perl will also be full of examples, as is anything to do with the Java regexp class. O'Reilly also has a book but doubt you'll need to go that far, there's plenty of Web-based reference sites!

I am looking for some guidance for developing patterns to help validate some form fields; for example I need to check that an entry is in the form
AA00
where AA are uppercase letters and 00 are two numbers.
If someone can help with this and, more generally, point me to a good resource for learning how to do this, I'd appreciate it.
