How to create an XML file from scratch ?

Question

Hi all,
I'm afraid that I will seem dummy, but I think I really misunderstand something or I'm trying to do something that is not possible...
I would like to create a XML file containing the following:<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="pl.xsl"?>
<!DOCTYPE playlist SYSTEM "pl.dtd">
<playlist id="2">
</playlist>I really need to have both the stylesheet and the DOCTYPE declarations... Does anyone know if this is possible ?
To create the XML Document, I am using the DocumentBuilder object from javax.xml package (jaxp-1.2-ea2). I think this, at least, is correct.
To print out the XML document I have tried to use :
- the Transformer from javax.xml package (jaxp-1.2-ea2) but I could obtain only the DOCTYPE declaration.
- the Serializer from Xerces parser (version 2.0.1) to print out the Document I am creating with the jaxp, but I was able only to obtain the stylesheet declaration...
So far I have just understand that there is a difference between Serializer and Transformer (one is serializing, and the other is transforming ;-)), but I couldn't figure out which one would be suitable to produce the XML file above...
I would really appreciate if one could help me with that ;-)
Thanks,
Karau

Could send me an example ?
For the moment I am using Transformer in that way:
     TransformerFactory tfactory = TransformerFactory.newInstance();
     try {
         Transformer transformer = tfactory.newTransformer();
         DOMSource source = new DOMSource(playlistDoc.getDocumentElement());
         StreamResult res = new StreamResult(new File(path));
         transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, PL_DTD);
         transformer.setOutputProperty(OutputKeys.INDENT, "yes");
         transformer.transform(source, res);
     catch (TransformerConfigurationException tce) {
         throw tce;
     catch (TransformerException te) {
         throw te;
     }
