Answer 1

The easiest way is to use a Transformer to do an default transform of the document from a DOMSource to a StreamResult.
something like
         TransformerFactory tf = TransformerFactory.newInstance();
         tf.setAttribute("indent-number", new Integer(4));
         Transformer t = tf.newTransformer();
         t.setOutputProperty(OutputKeys.INDENT, "yes");
         t.setOutputProperty(OutputKeys.METHOD, "xml");
         t.setOutputProperty(OutputKeys.MEDIA_TYPE, "text/xml");
         t.transform(new DOMSource(yourDOMDocument), new StreamResult(new OutputStreamWriter(yourFileOutputStream)));
