Camel Splitter with Xpath recognizes namespace, but returns null

[klua <pr...@citi.com>]

Hi,

I am using Camel's Spring DSL, to write a simple application, that takes
xml, and splits it based on the xpath. It should be pretty straightforward;
there is only one extra step that I have, which is declaring a namespace.
The problem is that although xpath recognizes the element that I'm looking
for, it returns a null for the value.
Here's a sample xml, to give you a general idea of what I'm doing. (Notice
that it has an associated namespace)

<foo:foo>

   <foo:bar>
      <foo:id idScheme="12345">1</foo:id>
   </foo:bar>

   <foo:bar>
      <foo:id idScheme="45678">2</foo:id>
   </foo:bar>

</foo:foo>

Here's my route:
<route>
    <from uri="direct:start">
    <split>
        <xpath>/foo:foo/foo:bar/</xpath>
        <to uri="mock:result"/>
    </split>
</route>

As I mentioned before, I declare the namespace, in the bean context of
spring. 
<beans...............................
 xmlns:foo="some URL"
 xmlns:bar="some URL"
>
And I get the expected number of results from xpath, but null values. Any
idea where I'm going wrong? Any help would be greatly appreciated! Thanks!

Did you had already a look on [1]? May one of the other possibilities works
for you:
- declaring the namespace on the camel context element (instead of the beans
element)
- specifying the xPath result type

[1] http://camel.apache.org/xpath.html

Best,
Christian

Hi,

could you try with a different xpath:

//bar

AFAIR, xpath can ignore the namespace.
