xpath does not match when namespace prefix changes

Hi all,

The question might seem simple, but I'm not able to figure the solution.

I need to extract the text node of a particular element. This is the sample xml document




I am using the following xpath to extract.



This is not extracting the value as the namespace prefix does not match. Is there a work around. It works if namespace prefix in the xpath is changed.

Thanks and Regards
Arjun

It doesn't matter whether the prefix is the same or different. What does matter is the namespace URI applied to the prefixes in the two places; that should be the same.

In the XML document I can see the namespace URI which is applied to the "ns" prefix. But I don't see the code where you apply a namespace URI to the "tns" prefix in your XPath expression. Perhaps you didn't apply any? If you are asking about a javax.xml.xpath.XPath object (you didn't mention that) then the setNamespaceContext method is how you do that.
