As *always* with xpath, make sure it works first.
For example set it to a header, and then use the camel tracer / log
component etc. to log it.
Also with xpath the result type is usually some XML type. And thus you
need to set it to "String" if you want just text.
There is a resultType on the xpath builder for that. Then you can set
it to String.class.
