RE: File name regular expression

Thanks Dennis. That was it. I kept the original expression and just
inserted a * after [A-Z0-9].

I have a question (or two) about your expression.

1) I re-read the wikipedia site and I get the * after [A-Z0-9], but I
don't get the * at the end. Shouldn't that be $ to look for .xml at
the end of the name?

Glad to help. Yes, that splat was a typo.

2) If the parenthesis are removed does ^ and $ still match the pfi_
and .xml strings respectively or just a single character?

Breaking this down: ^pfi_

String must begin with pfi_. Nothing can precede the p, f must follow the
p, ...
Same with the $ - the characters xml (in that order) must end the string.

I am not sure what you read that led you to believe the parentheses were
doing you some service. I will be happy to address and/or attempt to
interpret (translate) the phrase that led you that direction, if you can
find it.
