// This method applies the xslFilename to inFilename and
    // returns DOM document containing the result.
    public static Document parseXmlFile(String inFilename, String xslFilename) {
        try {
            // Create transformer factory

            // Use the factory to create a template containing the xsl file
            Templates template = factory.newTemplates(new StreamSource(
                new FileInputStream(xslFilename)));
    
            // Use the template to create a transformer
            Transformer xformer = template.newTransformer();
    
            // Prepare the input file
            Source source = new StreamSource(new FileInputStream(inFilename));
    
            // Create a new document to hold the results
            DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
