需要用到kxml2-2.2.2.jar包

要解析的XML文件内容：

<?xml version="1.0" encoding="UTF-8"?>
<persons>
<person id="1">
<name>张三</name>
<age>34</age>
</person>
<person id ="2">
<name>李四</name>
<age>24</age>
</person>
</persons>

Person.java文件内容

public class Person {

	private int id;
	private String name;
	private int age;
	public Person() {
		// TODO Auto-generated constructor stub
	}
	
	@Override
	public String toString() {
		return "Person [id=" + id + ",name=" + name + ",age=" + age + "]";
	}

	public Person(int id,String name,int age) {
		super();
		this.id = id;
		this.name = name;
		this.age = age;
	}
	public void setId(int id) {
		this.id = id;
	}
	public int getId() {
		return id;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getName() {
		return name;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public int getAge() {
		return age;
	}

}
