java 代码：public void loadFragment(String file) {
    try {
      DocumentBuilderFactory dbfactory = DocumentBuilderFactory.newInstance();
      DocumentBuilder builder = dbfactory.newDocumentBuilder();      Document d = builder.parse(new File(file));      Unmarshaller unmarshaller = new Unmarshaller(this.mapping);
      RegistryFragment fragment = (RegistryFragment) unmarshaller.unmarshal( (
          Node) d);      // this fragment as changed
      fragment.setChanged(true);      // if we get here, we successfully loaded the new fragment
      updateFragment(file, fragment);    }
    catch (Throwable t) {
      Log.error("RegistryService: Could not unmarshal: " + file, t);
    }
