Replace element by XPath - xpath

Question

I try to replace some element of my input XML in Citrus Framework.
My Spring context contains:
<citrus:namespace-context>
<citrus:namespace prefix="def" uri="http://sample.com/xmlns/2005"/>
</citrus:namespace-context>
My input file starts with:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<ns0:canonicalMessageHeader xmlns:ns0="http://sample.com/xmlns/2005">
<ns0:headerVersion>1.0</ns0:headerVersion>
<ns0:bodyVersion>1.0</ns0:bodyVersion>
<ns0:trackingInfo>
<ns0:eventHandlerInitInfo>
<ns0:processInfo>
<ns0:adapterTrackingId>214F27DF-E1FB-4E84-9122-390C5876ABD2:1</ns0:adapterTrackingId>
...
My endpoint is configured in that way:
<send endpoint="jms:topic:Order.Request?timeout=10000&connectionFactory=DEVconnectionFactoryFrom">
<message>
<resource file="com/sample/citrus/messages/input/SalesOrderTo.xml"/>
<element value="${track}" path="SOAP-ENV:Envelope/SOAP-ENV:Header/def:canonicalMessageHeader/def:trackingInfo/def:eventHandlerInitInfo/def:processInfo/def:adapterTrackingId"/>
I have the following error:
Can not evaluate xpath expression 'SOAP-ENV:Envelope/SOAP-ENV:Header/def:canonicalMessageHeader/def:trackingInfo/def:eventHandlerInitInfo/def:processInfo/def:adapterTrackingId'
at com/sample/citrus/SalesOrderToIT(sequential:45)
at com/sample/citrus/SalesOrderToIT(send:48-82)
Caused by: javax.xml.xpath.XPathExpressionException: org.apache.xpath.domapi.XPathStylesheetDOM3Exception: Prefix must resolve to a namespace: def
What's the possible cause of this error?
Best Regards

Answer 1

Global namespace declaration support is missing in Citrus when overwriting message elements in a send operation via XPath. This issue has been tracked: https://github.com/christophd/citrus/issues/331
In the meantime you have to use the exact same namespace prefix as in the message template file - in your case ns0:
Also you could throw away XPath overwrite and use the dot notated Node overwrite like this:
<send endpoint="jms:topic:Order.Request?timeout=10000&connectionFactory=DEVconnectionFactoryFrom">
<message>
<resource file="com/sample/citrus/messages/input/SalesOrderTo.xml"/>
<element value="${track}" path="Envelope.Header.canonicalMessageHeader.trackingInfo.eventHandlerInitInfo.processInfo.adapterTrackingId"/>
</message>
</send>
The dot notation is not based on namespaces but uses the local element names for finding the element in the message template. Obviously not as powerful as XPath but it works with current version of the framework.

You defined nso as namespace prefix in XML but then use def on the XPath, should be nso.
