[rules-users] RegEx in LHS

Hi all, i'd like to have following DSL conditions [condition][]Title contains {value}=title matches {value} [condition][]Title contains not {value}=title not matches {value} Currently (using Drools 4.0.3) it seems the parsers resolves to the first condtion and is matching the word "not" to {value}, so i tried [condition][]Title contains\s+{value}=title matches {value} [condition][]Title contains\snot\s{value}=title not matches {value} but this doesn't help, because second one again matches to the first rule ... also it is missing one parameter ... Any solutions? Cheers Markus
