JDOM has an XMLOutputter.
DOM Level 3 allegedly supports outputting from the DOM itself.
However if you don't want to use JDOM, and you don't have access to DOM Level 3, there is a way to do it using transformers. I'm not sure if this is a trick or whether it's considered the standard way to do it.
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
Document dom; // this is what you want outputted
OutputStream stream; // this is where you want it outputted
Transformer identity = TransformerFactory.newInstance().newTransformer();
identity.transform(new DOMSource(dom), new StreamResult(stream));Note that it's not actually much code if you keep the identity transform around for reuse. JDOM's approach is a lot simpler though. :-)
