Jaxp-Unable to remove an attribute permanently from document object

Question

Hi
I have a requirement where I have to strip out an attribute called "xmlns" at the root element of my xml document.
for eg: <UserProfile xmlns="http://foo">
<ID>1234</ID>
<Name>Bob</Name>
</UserProfile>
I tried using API's
1) document.getDocumentElement.removeAttribute("xmlns")
After this my xml document look like this
<UserProfile >
<ID>1234</ID>
<Name>Bob</Name>
</UserProfile>
Also tried this..
2) Attr att=document.getDocumentElement().getAttributeNode("xmlns");
att.setValue("");
document.getDocumentElement().setAttributeNodeNS(att);
After this my xml document look like this
<UserProfile xmlns="">
<ID>1234</ID>
<Name>Bob</Name>
</UserProfile>
Irrespective of all this , when I gave the new xml document to Jaxb for processing , Jaxb complains that
unexpected root element
uri:http://foo
Though this attribute neither visible nor accessible using any DOM apis, still this attribute exists as part of this document.
Could somebody explains a little more about this behaviour or help me to resolve this..
Any feedback will be deeply appreciated,
Ranjith Pillai.

Ranjith,
I am facing the same problem and still not been able to figure out what's wrong with parsing.
Here is the XML document before cleaning

Code to unmarshal
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
unmarshaller.setValidating(false);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new File( "test.xml"));
//Document doc = db.parse(inMessage);
cmcamList = (CamMessage )unmarshaller.unmarshal( doc );
//test.xml is actually the clean xml message as above.
Appreciate any help in resolving the problem.
Thanks,
