     callWriteXmlFile(doc,outwriter,"gb2312");
     outwriter.close();
     fos.close();
    } catch (Exception e) {
     e.printStackTrace();
    }
}
public static void main(String args[])
{
    writeXML w = new writeXML();
    String outfile = "D:/student.txt";
    w.writeXMLFile(outfile);

  }
    
}

上述方法可用于XML文档的初始化。
