RE: [xsl] How to select nodes with explicitly set default namespace - DOM4J

[omprakash.v@xxxxxxxxxxxxx]

Hi,
       What Mike wants you to do is  assign a prefix and use it to select
the node that you want. Just refer dom4j API documentation to select a node
in a namespace.  The following 2 lines may need changing:

 el.add(new Namespace("", "urn:hl7-org:v3"));         // include prefix
here
 Element interIdEl = (Element)(el.selectSingleNode("//interactionId"));
// use prefix here


If you need further justification, just read any of the threads relating to
namespace that has been posted the past few days.

Cheers,
Omprakash.V

The elements are not bound to any namespace prefix - as you can see from
the
example, so a default namespace of null or "" is used.  The namespace
"urn:hl7-org:v3" has no prefix, so the sub elements do not need the prefix,

how to I access such elements in code??

In XPath 1.0, if you want to select an element that's in a namespace, you
need to bind a prefix to that namespace and use a prefixed QName in the
path
expression. The fact that the namespace is the default namespace in the
source document makes no difference.
