One of the best regex resources are the PERL man-pages: http://www.perldoc.com/perl5.8.0/pod/perlre.html

However removing the * seems to have fixed things. I thought the * had to be in the mask expression in validation.xml because it was in all the examples I read in the docs. Where can I find a good Reg. Expression tutorial? Thanks.

(Obviously I have work to do on regular expressions.) Any assistance is appreciated.
