Need suggestion on JAXP DOM

Question

My tool is JAXP DOM. My idea is this: to realize XML file transfer between
two sockets. I finished several step so far at the sender side:
1. use DocumentBuilder to generate a new Document.
2. insert a root Element into the Document.
3. add new nodes into the root Element.
My question is how to do:
4. how to convert the Document type into OutputStream so I can send it out
using the socket. Maybe I should convert the Document into byte[] first or
something else, but how?
Thank you very much.

Answer 1

Thanks dude. Do you think I can do in this way:
TransformerFactory xformFactory = TransformerFactory.newInstance();
Transformer transformer = xformFactory.newTransformer();
DOMSource input = new DOMSource(myDocToSendOnSocket.getDocumentElement());
ByteArrayOutputStream baos = new ByteArrayOutputStream();
StreamResult output = new StreamResult(baos);
transformer.transform(input, output);
SSLSocket socket = (SSLSocket) SocketFactory.createSocket (address, port);
OutputStream out = new socket.getOutputStream();
out.write (baos.toByteArray());
out.flush();
out.close();
socket.close();
If the code is right, my question is: can I use baos.toByteArry(); directly? I mean baos is just one parameter in output's constructor. Does its value change after transform is called? Thank you.
