Default calling saxon from java program

Hello all,
       I'm working on a java function that has to appply and xslt file to an xml file.Both xml source file and xslt file are in form of a string and the target file must be returned as a string too.
Ive been looking at various examples but I could'nt make it work.

I wrote the following function.

private String XslTransform(String xmlSource , String xsl , String xmlTarget) throws Exception

            TransformerFactory factory = TransformerFactory.newInstance();
            Templates t = factory.newTemplates(new StreamSource(new File(xsl)));

            Transformer transformer = t.newTransformer();

            StreamResult target = new StreamResult(xmlTarget);
            transformer.transform(new StreamSource(xmlSource), target );

           return target.toString() ;

How should I tackle this problem?.
Am I using the correct functions??

Thanks in advance for the help.

If xmlSource and xsl are strings containing the actual XML text, rather than a filename or URL, then you should use

new StreamSource(new StringReader(xmlSource))

You may also need to call setSystemId() on the StreamSource object, if there are any URIs in the XML than need to be resolved.

It's not clear what xmlTarget is supposed to be. To return the result as a string, do

StringWriter sw = new StringWriter();
transformer.transform(source, new StreamResult(sw));
return sw.toString();
