How can I get the saxon implementation to work without specifying the namespace (i.e. XPathExpression expr = xpath
.compile("/ClientRoot/Client/Policy/Identification/ProductIdentifier")

Hi Dian,

I tried the first code as is on saxon but it doesn't return any nodes. I had to do it the second way on saxon to get it to work. My question is how do I get the first code to work with saxon.


Regards,

Brian

I got around my problem with the following;

XPathFactory factory = new org.apache.xpath.jaxp.XPathFactoryImpl();
			XPath xpath = factory.newXPath();

Actually, this is what i really wanted to do. The jar for saxon is included in the project, but I wanted to use this implementation.
