[basex-talk] confused

Hi, I'm confused. The code below results in false() for $e1 and true() for $e2. Shouldn't both be false? I must be overlooking something. Can somebody enlighten me, please? let $node := <node ID="X"><node ID="Y"/></node> let $e1 := exists( trace( $node/node[ ./@ID = "Z"], 'node: ')) let $e2 := exists( $node/node[ ./@ID = "Z"] ) return ( $e1, $e2) Thnx in advance, Rob Stapper --- Dit e-mailbericht bevat geen virussen en malware omdat avast!
