DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(new File("data.xml"));

SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
parser.parse(new File("data.xml"), new DefaultHandler() {
    // обработчики событий
});

JAXBContext context = JAXBContext.newInstance(Employee.class);
Unmarshaller unmarshaller = context.createUnmarshaller();
Employee emp = (Employee) unmarshaller.unmarshal(new File("employee.xml"));
