Thanks for the reply. Could you give me an example for 1c? I mocked up an
example. Assume the below XML comes from the ftp site. The XMLFilter's match
method accepts the username. How can I use XPath to pass the user to the match
method?
<Example>
<User>joe</User>
</Example>
Class XMLFilter{
public boolean match(String username){
//check db for user
//if found return true/else false
}
}
<route>
<from>"ftp://rider.com/orders?username=rider&password=secret";</from>
<filter>
<simple>${bean:xmlFilter?method=match}</simple>
<to uri="log:worked"/>
</filter>
</route>
Thanks

Yes xpath works fine for grabbing content from a XML doc.
However where it get tricky is if your XML uses namespaces. If so
your XPath expression *must* also use namespaces.

You can use a Content Based Router, and in the otherwise leg, you can
use the stop DSL.

Yes this happens already, the filter predicate is just for determine
