xpath filter question

[John Dubchak <jo...@johndubchak.com>]

Hi,

I am trying to create a JavaDSL route that filters an incoming XML from 
an ActiveMQ queue.  The message is being delivered correctly and I can 
print it out if I short-circuit it with a processor that dumps the 
message.  However, removing the processor, I cannot seem to get the 
correct xpath expression to match on a particular value:

from("activemq:cdw.Notifications")
   .filter()
.xpath("/parent_node[child_node = 'value of text']")

Any insight into what I've messed up?

Thanks,
John

Getting xpath expression correct can be tricky. You can use some xpath
eval tool to try this to make sure to get the exp correct.

And mind about namespaces, if the xml has namespaces then its even more tricky.

Some details here
http://camel.apache.org/xpath

And then search the web for java xpath with namespaces how to do that.

Can you share the sample xml message ? Does it have namespace in it ?
