AFAIK there is no regular expression facility in the SDK.
I guess that for such a simple task you are far better off writing your
own validation routine (it is exceptionally simple and it will be much
faster and smaller than a more general regular expression package).
Anyway if you still need regular expressions you can easily port one
of the many freely-available implementations. Some pointers:
Ozan Yigit's very *small* implementation:
http://www.cs.yorku.ca/~oz/regex.shar
Perl Compatible Regular Expressions (PCRE):
http://www.pcre.org
GNU rx (GPL license):
http://www.gnu.org/software/rx/rx.html
(I'd go for the first one, it's the smaller and perhaps the most
easy to port).
