  public static void main(String[] args) throws Exception {
    XMLOutputFactory outputFactory = XMLOutputFactory.newInstance();
    XMLEventFactory eventFactory = XMLEventFactory.newInstance();
    XMLEventWriter writer = outputFactory.createXMLEventWriter(System.out);

    writer.add(eventFactory.createStartDocument("UTF-8", "1.0"));
    writer.add(eventFactory.createStartElement(new QName("p"), null, null));
    XMLEvent sampleElement = eventFactory.createStartElement("", null, "s",
        null, null);
    writer.add(sampleElement);
    writer.add(eventFactory.createEndElement("", null, "s"));
    writer.add(sampleElement);
    writer.add(eventFactory.createEndDocument());
    writer.flush();
