Re: [rules-users] matches operator
As the Expert manual has it: a matches b a is any string, b is a string containing a regular expression See java.util.regex.Pattern for more documentation. The matches operator works via the method Matcher.matches, so looking for xyz anywhere in a string will require a pattern like .*xyz.*. -W On 11 March 2012 12:18, shawn youngxiao...@hotmail.com wrote: Hey there. I get stuck on using matches operator. The Documentation doesn't say the operator in details. I just need to find whether String2 contains String1 (Ignore Case). Now I have a key(String variable) and a value(String variable). If I write key matches value, I know it definitely wrong. So is there anyone knows how to write it? Cheers.

Re: [rules-users] matches operator
Thanks for your reply. Is this means I can't match two string variables? Only match a string constant with a string variable? -- View this message in context: http://drools.46999.n3.nabble.com/matches-operator-tp3816492p3816818.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] matches operator
IIRC you can match a variable with a constant. You might be able to achieve what you require with a custom operator. Unfortunately I am not the one to advise how to write or configure a custom operator :( sent on the move On 11 Mar 2012 15:39, shawn youngxiao...@hotmail.com wrote: Thanks for your reply.

Re: [rules-users] matches operator
The second operand of matches is just another String expression, and therefore it could be a string literal, a variable bound to a String field, or a String expression. For instance, this $f1: Foo( $id1: id ) $f2: Foo( this != $f1, $id2: id matches .* + $id1 + .* ) is a test for $id2 being a substring of $id1. Or you could do $f1: Foo( $id1: id ) $f2: Foo( this != $f1, $id2: id matches .*( + $id1 + )\\1.* ) which tests - what? -W On 11 March 2012 17:39, shawn youngxiao...@hotmail.com wrote: Thanks -- View this message in context: http://drools.46999.n3.nabble.com/matches-operator-tp3816492p3816900.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

RE: [rules-users] matches operator
Also, Java is far stricter on syntax for regular expressions than anything else I've seen. You can't just test your stuff at a unix prompt or using grep to see if it works. That's just the first step. I generally use the vi find command. _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Proctor Sent: Monday, July 09, 2007 7:16 AM To: Rules Users List Subject: Re: [rules-users] matches operator Read up on regular expression, what you just wrote there is not valid.
