ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); Source xmlSource = new DOMSource(doc); Result outputTarget = new StreamResult(outputStream); TransformerFactory.newInstance().newTransformer().transform(xmlSource, outputTarget); InputStream is = new ByteArrayInputStream(outputStream.toByteArray());
