rule "PatternTest"
        when
                $pli:Item( eval(title.matches("^Test\s*")) )
        then
                        #
end

Having a second look i realize that the DroolsParser should not parse
the pattern string because it's java code ... and i can't use title
matches "^Test\s*" because title may have chars like (,\ and so on
that resolves into a RuntimeException (sth. with Groups not closed in
RegEx).

Cheers

Markus
