yes take a look @ the javax.xml.transform.Result interface and it's implementations in packages javax.xml.transform.stream ( for ur case sicne you want to serialize), javax.xml.transform.dom, javax.xml.transform.sax, But you w'd be required to do a transformation! on the XML file that you have in memory. Then use an identity stylesheet (ie invoke the no-argument newTransformer() method to obtain the TransformerFactory instance) and then do a transform() providing the appropriate implemenation of the Result interface. You can use StreamResult for your case. I guess that's the only way you can serialize a in-meomory xml to a file using "JAXP". Ofcourse parsers provide better ways of serializing the in-memory representation of XML file which in turn are not portable across parsers.
