I'm writing an application in which I want to base decisions partly on
whether or not attributes match regular expressions. For example, I
might want to match regular expression "Pe*er" with the fact "(town
(name Peterboro))."
so that, if I executed something like the following statements
(deftemplate town (slot name)(slot state))
(assert (town (name Peterboro)(state NH)))
(assert (town (name Paulsboro)(state NJ)))
(defrule regexp-rule
(town (name "Pe*er")(state ?st))
=>
(prinout t "The state I wanted was " ?st "." crlf))
(run)
I would get the output
"The state I wanted was NH."
I know that I can write code in Java or execute an external program
(e.g. egrep) to do this, but I would like to do it entirely within
Jess if I can.
I haven't found any clues either in the Jess Manual or in the CLIPS
books I've checked, but I may not yet know enough about CLIPS to be
looking for the right things.
Thanks!
Peter Olsen
