Jess doesn't include regular expression matching. It'd be easy to
build a set of userfunctions around the gnu.regex package, though, for
example, if you really needed it. See http://www.cacas.org/~wes/java/,
the home page for gnu.regex.
For the examples below, though, you don't need regular expressions;
perhaps if your needs aren't more complex than this then all you need
is to use a bit of reflection to invoke the primitive matching
capabilities of the Java String class.
(defrule stewar-names
(person (last-name ?n&:(call ?n startsWith "stewar")))
=>
(printout t "?n "starts with 'stewar'" crlf))
