Namespaces with JDOM Posted: Jul 27, 2004 2:32 AM

Hi,

I need some help with JDOM. I am trying to use XPath in JDOM. Can I set the namespace without setting a prefix. I know there is an API which is getNamespace(java.lang.String uri). My code looks something like this :

XPath xpath = XPath.newInstance("/PrescriptionHeader/id/@root");
org.jdom.Namespace ns = org.jdom.Namespace.getNamespace("urn:hl7-org:v3");
xpath.addNamespace(ns);
Stri ng str = (String) xpath.selectSingleNode(document);

This however does not return the desired result, however if
I tweak the code to look like this:

XPath xpath = XPath.newInstance("/foo:PrescriptionHeader/foo:id/@root");
org.jdom.Namespace ns = org.jdom.Namespace.getNamespace("foo","urn:hl7-org:v3");
xpath.addNamespace(ns) ;
String str = (String) xpath.selectSingleNode(document);

This returns the proper result. I just want to know why the first solution isn't working.

I am using JDOMB-10

Any help would be appreciated.

Thanks & Regards,
Abhishek
