Axiom remove namespace printing OMElement

[Arnaud MERGEY]

Hi,

I  need to print an OMElement in file, I have found this code.
OMElement response=......
 //Print result in a file
FileWriter writer=new FileWriter(pResultFile,pAppend);
response.serialize(XMLOutputFactory.newInstance()
                 .createXMLStreamWriter(writer));


Can I clean result xml removing namespace and prefix with Axiom (I'd 
prefer don't use XSLT transformation).

for example I want <pre:tag></pre:tag> be printed <tag></tag>

thanks for yout help
Arnaud
