Can you test that very particular example on your Camel installation? Make sure you add the resultType attribute on the xpath element, i.e. resultType="java.lang.String". Otherwise it is assumed that the result will be a NodeList which it isn't in this case.
It looks like we may have lost the culprit of this error due to oversimplification of the example for posting. On the other hand, if it actually fails on your environment, please post the version of Camel you are running on and more details of the environment ;) On 7 December 2011 20:45, MichaelAtSAG <[email protected]> wrote: > I receive errors when trying to use xpath functions.
