Here are two ways to write the regular expression. m : Customer( age matches "(18|21|33|28|40|41)")
m : Customer( age matches "(18|2[18]|33|4[01])") Did you try m : Customer( age in ("18","21","33","28","40","41")) I don't know which solution is faster. I think that would be an interesting test. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
