This is starting to drive me nuts…

Say, I have the hypothetical xml object:  
[AS]var testXML:XML = \<rootNode xmlns=“[http://www.somedomain.com/](http://www.somedomain.com/)”\>  
\<blah\>Some node\</blah\>  
\<yadda\>Some other node\</yadda\>  
\</rootNode\>[/AS]

and I want to traverse that xml using e4x.

Now, it’s relatively easy to say:  
[AS]namespace ns = “[http://www.somedomain.com/](http://www.somedomain.com/)”;  
trace (testXML.ns::blah); // traces Some node[/AS]

But what if, in theory, I don’t know the namespace uri. The question is: is there a way to declare a namespace using the namespace from an xml object?

I’ve tried:  
[AS]namespace ns = testXML.namespace() as Namespace;  
trace (testXML.ns::blah);[/AS]

but that throws the error:

> 

1171: A namespace initializer must be either a literal string or another namespace.

which doesn’t make any sense as  
[AS](testXML.namespace() as Namespace) is Namespace[/AS]  
returns true. Which seems, at least in my mind, to mean that my namespace initializer \*is \*another namespace.

Any suggestions or ideas greatly appreciated…
