Hi folks !
has anyone got an idea how to implement some sort of pattern matching
in Jess ? I have thought about e.g. regular expressions or the like.
I have some lengthy error messages I need to analyze and at the moment
I´m using structures like these:
(defrule ...
(fact ... ?variable)
=>
if (eq (str-index "my pattern" ?variable) TRUE)
(do this)
else
(do that) )
)
But IMHO this contradicts any style guide for writing
good rules.
I think it would be a better solution to do it like this:
(defrule #1
(fact .... ?variable(*my pattern*))
=>
(do this) )
(defrule #2
(fact ...)
=>
(do that) )
Thanks in advance for any help.
