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>

JavaBean：

package com.pull.domain;  
      
    public class Person {  
      
        private int id;  
        private String name;
