Person实体类：

1 package com.icss.bean;  2  3 public class Person {
    4     private int id;  5     private String name;  6     private int age;  7     public int getId() {
    8         return id;  9     } 10     public void setId(int id) {
   11         this.id = id; 12     } 13     public String getName() {
   14         return name; 15     } 16     public void setName(String name) {
   17         this.name = name; 18     } 19     public int getAge() {
   20         return age; 21     } 22     public void setAge(int age) {

   32         super(); 33     } 34     @Override 35     public String toString() {
   36         return "id="+id+"  name="+name+"  age="+age; 37     } 38 39 40     41 }

SAX解析方式  SAX帮助类：

       extends DefaultHandler {
   14     private List
      
        list; 15     private Person p; 16     String nameflag; 17 18 19     public List
       
         getList() {
   20         return this.list; 21     } 22 23     @Override 24     public void startDocument() throws SAXException {
   25         this.list = new ArrayList
        
         (); 26     } 27 28     @Override 29     public void endDocument() throws SAXException {
