[jdom-interest] bug in Element.getCopy ?

[Jochen Strunk]

Hi,

that's not what I meant. I wanted to change the default namespace of an 
element. The only
way I found to do so is via the getCopy Method:

Element a = 
oldA.getCopy(oldA.getName(),Namespace.getNamespace("http://www.x.org");

I'd expect the result to be:

<a xmlns="http://www.x.org">
    <b></b>
</a>

because I created b with no namespace.

But the result is:

<a xmlns="http://www.x.org">
    <b xmlns=""></b>
</a>

because b has an empty namespace.

I think applying a default namespace to an element should also apply that 
namespace to every child element with no namespace.
This does not work because in that case jdom seems to not properly separate 
between the empty namespace and no namespace.

Any suggestions on this ??

The patch I posted does not really solve this problem, it simply sets the 
given namespace on all child elements which is certainly incorrect 
behaviour in most cases.
