How to write a DOM Document to an xml file in java 1.5

private void writeXMLDocument(final Document doc, final String fileName) throws IOException {

// open output stream where XML Document will be saved

File xmlOutputFile = new File(fileName);

FileOutputStream fos;

Transformer transformer;

fos = new FileOutputStream(xmlOutputFile);

// Use a Transformer for output

TransformerFactory transformerFactory = TransformerFactory.newInstance();

transformerFactory.setAttribute("indent-number", new Integer(4));

try {

transformer = transformerFactory.newTransformer();

transformer.setOutputProperty(OutputKeys.INDENT, "yes");

transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC, "-//Hibernate/Hibernate Mapping DTD 3.0//EN");

transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd");

transformer.setOutputProperty(OutputKeys.ENCODING, "ISO-8859-1");

} catch (TransformerConfigurationException e) {

logger.error("Transformer configuration error: " + e.getMessage());

throw new IOException(e.getMessage());

}

DOMSource source = new DOMSource(doc);

StreamResult result = new StreamResult(new OutputStreamWriter(fos, "utf-8"));

// transform source into result will do save

try {

transformer.transform(source, result);

} catch (TransformerException e) {

logger.error("Error transform: " + e.getMessage());

}

}
