Re: [rules-users] Iterating two collection in LHS

You should really insert your males and females into your working memory instead of having them as nested lists only. Anyway: rule "unlucky male" where $c : City() $m : Male( $age : age ) from $c.maleList not( Female( age ==$age ) from $c.femaleList ) then // $m is unlucky, no female with the same age end []s Edson 2009/2/2 techy <techluver007(a)gmail.com&gt; > > Hello, > > Please help me to implement following rule in drool.
