[rules-users] are for loops possible in drools

does anybody know if there is a way to do for loops in drools ?. I am trying to loop through a list of string to see if one of the strings matches a pattern e.g. def listOfStrings = ['a','a.b','a.b.c'] for(String s:listOfStrings){ if(s matches "^a.b.*$"){ return true } } I have written the following rule based on what documentation I could find, but I dont think the syntax is correct rule "Matcher" when TestClass : TestClass(($s matches "^a.b.*$") from listOfStrings, count($s)) then TestClass.setResponse( "Condition is True !!" ); end I am finding it hard to find good documentation on the drl language I would appreciate any help that anybody can give me -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/are-for-loops-possibl...
