Counting StyleSheep [was XalanJ200 Stylesheet requires attribute: version]

[Christopher Hull <ch...@mediagate.com>]

I've got some more detail on this bug.  Turns out it only happens when 
you create a Transformer from a SourceDOM.

Here's the code, taken from the DOM2DOM sample.



	public static void main(String[] args)
     throws TransformerException, TransformerConfigurationException, 
FileNotFoundException,
            ParserConfigurationException, SAXException, IOException
   {
	  TransformerFactory tFactory = TransformerFactory.newInstance();

     if(tFactory.getFeature(DOMSource.FEATURE) && 
tFactory.getFeature(DOMResult.FEATURE))
     {

       //Instantiate a DocumentBuilderFactory.
       DocumentBuilderFactory dFactory = 
DocumentBuilderFactory.newInstance();

       //Use the DocumentBuilderFactory to create a DocumentBuilder.
       DocumentBuilder dBuilder = dFactory.newDocumentBuilder();

	  // Process the stylesheet StreamSource and generate a Transformer.
       // Transformer transformer = tFactory.newTransformer(new 
StreamSource("birds.xsl"));
	
	  // This will throw a misleading exception.
	  Document xslDoc = dBuilder.parse("birds.xsl");
	  System.out.println("\n\n!!!!!!!!!  About to throw a vast Exception 
!!!!!!!!!!!!!!\n\n");
	  Transformer transformer = tFactory.newTransformer(new DOMSource(xslDoc) );
	
       //Use the DocumentBuilder to parse the XML input.
       Document doc = dBuilder.parse("birds.xml");

       // Use the DOM Document to define a DOMSource object.
       DOMSource domSource = new DOMSource(doc);

       // Set the base URI for the DOMSource so any relative URIs it 
contains can
       // be resolved.
       domSource.setSystemId("birds.xml");

       // Create an empty DOMResult for the Result.
       DOMResult domResult = new DOMResult();

   	  // Perform the transformation, placing the output in the DOMResult.
       transformer.transform(domSource, domResult);
	
	    //Instantiate an XML serializer and use it to serialize the output 
DOM to System.out
	    // using a default output format.
       Serializer serializer = SerializerFactory.getSerializer
 
(OutputProperties.getDefaultMethodProperties("xml"));
       serializer.setOutputStream(System.out);
       serializer.asDOMSerializer().serialize(domResult.getNode());
	}
     else
     {
       throw new org.xml.sax.SAXNotSupportedException("DOM node 
processing not supported!");
     }
   }
