        // later in this code */ URL         xslInput = new

        //   The result of the transformation can be one of
        //   the following:
        //
        // 1. Return a XMLDocumentFragment
        // 2. Print the results to a OutputStream
        // 3. Report SAX Events to a ContentHandler
 
        // 1. Return a XMLDocumentFragment
        XMLDocumentFragment res;
        res = processor.processXSL(stylesheet, xmlInput);
 
        // Print the result to System.out
        res.print(System.out);
 
        // 2. Print the results to a OutputStream
        // processor.processXSL(stylesheet, xmlInput,
        // System.out);
 
        // 3. Report SAX Events to a ContentHandler
        // ContentHandler cntHandler = new
        // MyContentHandler();
        // processor.processXSL(stylesheet, xmlInput,
        // cntHandler);
 
        // Display message for successful execution
        System.out.println("Executed Successfully");
