XPathBuilder Does not work when a Namespace is present in XML message

Hello,
I am new CAMEL user facing diffculty in getting my XPAT matched to my input
XML.
Below is the pice of code whith I uses to find if the Exchange has the
matching Xpath

private boolean isBusinessObjectMatches(final Exchange exchange)
{
	final String expression =
"/EventMessage/MessageHeader/BusinessObjectName='Adjustment'";
             final XPathBuilder xpathBuilder =
XPathBuilder.xpath(expression);
	return xpathBuilder.matches(exchange))
}

Here is my input message which is present in the Exchange, for this the
xpathBuilder.matches(exchange))always returns false. 
<?xml version="1.0" encoding="UTF-8"?>
<EventMessage xmlns="http://www.basis.ko.com/XMLSchemas/EventMessage/2.0"
xmlns:docu="http://www.basis.ko.com/XML/2002/SchemaDocumentation"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.basis.ko.com/XMLSchemas/EventMessage/2.0
C:\DOCUME~1\N13112\MYDOCU~1\workspace\EVENTD~1\Mappings\BasisSchemas\Modified\EventMessage_Adjustment.xsd">
	<MessageHeader>
		<EventMessageID>AdjustmentUpdated</EventMessageID>
		<BusinessObjectName>Adjustment</BusinessObjectName>
		<Action>update adjustment</Action>
	</MessageHeader>
<EventMessage>

But for when I remove the name space from my input XML the
xpathBuilder.matches(exchange)) work fine example
<?xml version="1.0" encoding="UTF-8"?>
<EventMessage>
	<MessageHeader>
		<EventMessageID>AdjustmentUpdated</EventMessageID>
		<BusinessObjectName>Adjustment</BusinessObjectName>
		<Action>update adjustment</Action>
	</MessageHeader>
<EventMessage>

Can any one please let me know why this is happening and how to
xpathBuilder.matches(exchange))  to work with the namespace in the input
message?

Check up with XPath in the JDK as its basically that what is used.
And maybe check some of the unit tests in Camel.
And as always we love contributions for both the code and wiki documentation.


And besides XML + namespaces + XPATH is not only my list of technology
stack which is so fun to mess with that I want to do that in my spare
time :)

Claus,
I saw that. the issue my input xml comes with no prefix, For which I tried
to add the below code
xpathBuilder.getNamespaceContext().add(null,
"http://www.basis.ko.com/XMLSchemas/EventMessage/2.0")

But the problem is not resolved. Is there a way to make the route namespace
aware to false?

Hi

You have to pass in Namespaces to the XPathBuilder.

See the section Namespaces on its wiki page
http://camel.apache.org/xpath
