[jdom-interest] XPath / default namespace

[Rob Henley]

With beta9 I'm trying to use XPath against a document with a default 
namespace such as:

<?xml version="1.0" encoding="UTF-8"?>
<definitions name="name1" xmlns="http://my/standard/">
    <AAA>aaa1</AAA>
    <AAA>aaa2</AAA>
</definitions>

Without the default namespace in the document, this works fine:

XPath xpath = XPath.newInstance("//AAA");
List results = xpath.selectNodes(myDocument);

With the namespace in the document, the above code returns an empty list.

If I try:

XPath xpath = XPath.newInstance("//*");
List results = xpath.selectNodes(myDocument);

... I get the three elements. AAA for instance is returned with namespace 
"http://my/standard/" and qualified name AAA.


I tried various ways of prefixing the element with the namespace without 
luck. I also tried:

XPath xpath = XPath.newInstance("//AAA");
xpath.addNamespace("","http://my/standard/");

and ...

XPath xpath = XPath.newInstance("//N:AAA N http://my/standard/");

(The latter was based on an MSDN article: 
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnexxml/html/xml05202002.asp).

Both return an empty list. 

Can anyone point me in the right direction?

Cheers
Rob
