Unparsing a DOM tree and write XML to file

Question

Hi,
I have created a DOM tree from scratch and would like to unparse the DOM tree and write the XML to a file, but how do I do that?
Does anybody got code examples that do this?
All help are very appreciated!

Thank you very much for the hint! Unfortunaly I still got problem to get it work though.
I made a little piece of test code to try it but during the execution of the "Transformer.transform(source,result)" method I gets an "org.w3c.dom.DOMException".
Does anybody see what that problem might be cause of by exmining the code below?
I also would like to know how to specify the location where I would like to print out the XML file.
Here is my little piece of test code:
try{
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFadctory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
doc.appendChild(doc.createElement("topLevel"));
Element elm = doc.getDocumentElement();
elm = (Element)elm.appendChild(doc.createElement("PersonData"));
elm = (Element)elm.appendChild(doc.createElement("Name"));
elm.setAttribute("Firstname","D");
elm.setAttribute("Lastname", "D");
DOMResult result = new DOMResult(doc);
DOMSource source = new DOMSource(doc);
TransformerFactory transformerFactory = TansformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.transform(source,result);
}catch(ParserConfigurationException e) {
}catch(IOException e) {
}catch(TransformerException te) {
