XSLT dynamic XML data serverSide. NO External XML file

Question

I am developing a web application currently using Tomcat 3.2.4, latest Xereces and Xalan.
I have a JSP page that 1st includes a HTML menu, I then wish to include a JSP page that will produce XML data. I would like to apply an XSLT to this XML data serverSide.. All of the solutions I have seen to date refer to a static XML file.. whereas the data in my XML structure is dynamic..
If anyone could please lend a hand it would be greatly appretiated.
Evan.

Sample code for transforming xmlstring
public String transformXML(String xmlString, String screenName) {
Document document;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
StringWriter stw = new StringWriter();
try {
//File stylesheet = new File(uc.getXSLName(screenName));
File stylesheet = null;
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse(new InputSource(new StringReader(xmlString)));
StreamSource stylesource = new StreamSource(stylesheet);
StreamResult result = new StreamResult(stw);
result.setWriter(stw);
DOMSource source = new DOMSource(document);
// Use a Transformer for output
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(stylesource);
transformer.transform(source, result);
return stw.toString();
catch (Exception e) {
System.out.println(e);
return null;
}
