StusXml檔案自動建立：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<stus>
	<stu id="t01" name="小明">
		<address>湖北</address>
	</stu>
	<stu id="t11" name="小明">
		<address>天津</address>
	</stu>
	<stu id="t21" name="胡六">
		<address>湖南</address>
	</stu>
	<stu id="t31" name="李四">
		<address>湖南</address>
	</stu>
	<stu id="t41" name="小明">
		<address>河北</address>
	</stu>
	<stu id="t51" name="王五">
		<address>湖北</address>
	</stu>
	<stu id="t61" name="李四">
		<address>河北</address>
	</stu>
	<stu id="t71" name="王五">
		<address>天津</address>
	</stu>
	<stu id="t81" name="王五">
		<address>新疆</address>
	</stu>
	<stu id="t91" name="胡六">

StudentJava檔案：

package com.briup.DOMXML;

public class Student {
	private String id;
	private String name;
	private String address;

	public String getId() {
		return id;
	}

	public void setId(String id) {
