public class ProcessingInstructionLister extends DefaultHandler
{
	public void processingInstruction(String target, String data)
	{
		System.out.println("Processing Instruction");
		System.out.println("  target: "+target);
		System.out.println("  data:   "+data);
		System.out.println();
	}
	public static void main(String[] args)
	{
		try
		{
			XMLReader parser = XMLReaderFactory.createXMLReader(
				"org.apache.xerces.parsers.SAXParser"
			);
			ContentHandler handler = new ProcessingInstructionLister();
			parser.setContentHandler(handler);
			for(int i=0;i<args.length;i++)
			{
				parser.parse(args[i]);
			}
