Camel Content based router with XPath not working

Question

I'm implementing a content based router in camel using XPath. But for some reason the XPath expression doesn't evaluate the content and always the otherwise path is chosen. This is the route I defined in my camel-context:

<route>
        <from uri="cxf:bean:hioServiceEndPoint"/>
        <process ref="hioProcessor"/>
        <inOnly uri="file:{{path.ws.data}}/incoming/hio?fileName=hio_${date:now:yyyyMMdd_HHmmssSS}.xml"/>
        <choice>
            <when>
                <xpath>//ORDER_TYPE = 'CROSSDOCKING'</xpath>
                <log message="NIELS Incoming CROSS HIO !!!"/>
                <to uri="jms:incomingHioCross"/>
            </when>
            <otherwise>
                <to uri="jms:incomingHio"/>
                <log message="NIELS Incoming HIO"/>
            </otherwise>
        </choice>
        <transform>
            <constant>OK</constant>
        </transform>
</route>

And this is the XML which needs to be searched for the tag ORDER_TYPE:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<INBOUND_ORDER xmlns="urn:ifsworld-com:schemas:handle_inbound_order">
    <DELIVERY_LEADTIME>0.0</DELIVERY_LEADTIME>
    <DELNOTE_DATE>2010-12-15T00:00:00</DELNOTE_DATE>
    <DELNOTE_NO>1454</DELNOTE_NO>
    <DESPATCH_DATE>2010-12-15T16:39:43</DESPATCH_DATE>
    <ORDER_DATE>2010-12-15T16:39:43</ORDER_DATE>
    <ORDER_NO>1454</ORDER_NO>
    <ORDER_TYPE>CROSSDOCKING</ORDER_TYPE>
    <REMARKS xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
    <SITE>DC2</SITE>
    <VENDOR_NO>ALM</VENDOR_NO>
    <INBOUND_ORDER_LINES>
        <INBOUND_ORDER_LINE>
            <CURRENCY_CODE>EUR</CURRENCY_CODE>
            <PART_NO>1276.1</PART_NO>
            <QUANTITY>2.0</QUANTITY>
            <QUANTITY_UNIT_MEAS>PCS</QUANTITY_UNIT_MEAS>
            <REMARKS xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
            <SEQUENCE_NO>1.0</SEQUENCE_NO>
            <UNIT_PRICE>0.0</UNIT_PRICE>
        </INBOUND_ORDER_LINE>
    </INBOUND_ORDER_LINES>
</INBOUND_ORDER>

I can't see what I'm doing wrong, I also tried /INBOUND_ORDER/ORDER_TYPE = 'CROSSDOCKING' but even then I can seem to get It working. I wrote a test case to see if my XPath expression is correct and that works fine and returns true.

I'm using camel 2.5.0.

So if anybody has a tip, I would appreciate it.

This is the most FAQ in XPath. Just search for "XPath and default namespace" and you will find tons of good explanations and solutions to the problem. In a nutshell, you need to "register a namespace" and use its prefix (say `"x"`) so that your expression will become: `//x:ORDER_TYPE = 'CROSSDOCKING'` — Dimitre Novatchev, Sep 05 '12 at 12:16
Yeah XPath and namespaces is a common problem to get working together. You can also maybe just search the XML as a String for the content of CROSSDOCKING, as a kind of test. For example with the Camel Simple language: ${body} contains 'CROSSDOCKING' — Claus Ibsen, Sep 05 '12 at 13:28

I'm a little bit confused by your namespace xmlns="urn:ifsworld-com:schemas:handle_inbound_order". Is it a valid namespace?

Anyway, I think this should work:

//*[local-name() = 'ORDER_TYPE'][codepoint-equal(text(), 'CROSSDOCKING')]
