I must admit I use a custom implementation of xPath to solve my issues with notification messages. One word of caution the duplicate namespace found when using the current xml parser (the .toXml() ) function, caused some problems with my custom xPath implementation, but was solved after I removed the duplicate namespace (seems always to be xmlns:wsnt="http://docs.oasis-open.org/wsn/b-2";).
