-- 紧急求救！十万火急！！！如何在DTD限制下产生xml文件？
我现在遇到这么一个问题，从数据库中读出数据，然后在一个已有的DTD文件的约束下将这些数据保存在一个XML文件中，请问各位大虾如何解决呢？十万火急！！！在线等！！！多谢了！
，下面是我写的源代码，不知道为什么文中的DTD文件对结果不起作用，晕死了！import java.sql.*;
import java.io.*;
import org.jdom.*;
import org.jdom.output.*;
public class JDOMBuildXMLDoc {
public void BuildXMLDoc(OutputStream out) throws IOException, JDOMException {
Element eeeRoot, eee1, eee2;
Document Doc;
DocType DocT;
eeeRoot = new Element("employees_information");
Doc = new Document(eeeRoot);
DocT = new DocType("employees_information", "DTDTest.dtd");
Doc.setDocType(DocT);
try {
conn connDbBean = new conn();
ResultSet RS_result = connDbBean.executeQuery("select * from employ");
String name = "";
String emp_id = "";
String age = "";
String sex = "";
String address = "";
String email = "";
String tel = "";
Element eee3;
while (RS_result.next()) {
name = RS_result.getString("name");
emp_id = RS_result.getString("emp_id");
age = RS_result.getString("age");
sex = RS_result.getString("sex");
address = RS_result.getString("address");
email = RS_result.getString("email");
tel = RS_result.getString("tel");
eeeRoot = Doc.getRootElement();
eee3=new Element("employs_data");
eeeRoot.addContent(eee3);
eee1 = new Element("name");
eee2 = eee1.setText(name);
eee2 = eee1.addAttribute("emp_id", emp_id);
eee1 = eee3.addContent(eee2);
eee1 = new Element("age");
eee2 = eee1.setText(age);
eee1 = eee3.addContent(eee2);
