PULL解析XML

XML：

<?xml version="1.0" encoding="UTF-8"?>
<persons>
    <person id = "23">
        <name>张老师</name>
        <age>21</age>
    </person>
    <person id = "20">
        <name>李老师</name>
        <age>25</age>
    </person>

</persons>

 

Person类：

package com.pull.domain;

public class Person {

    private int id;
    private String name;
    private int age;

    public int getId() {
        return id;
    }

    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 String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public Person() {
        // TODO Auto-generated constructor stub
    }

    @Override
    public String toString() {
        return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
    }

}

PullXMLTools类：
