Android--使用XMLPull解析xml

在Android中极力推荐的xmlpull方式解析xml。xmlpull不仅仅可以使用在Android上，同样也适用于javase，但在javase环境下，你需要自己去获取xmlpull所依赖的类库。
        环境：        

    kxml2-2.3.0.jar

    xmlpull_1_1_3_4c.jar

以上两个jar分别从以下网站下载:

http://www.xmlpull.org/    xmlpull

http://kxml.sourceforge.net/    kxml

xml文件:

[html] view plain copy

 print?

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <root>  
3.     <student id="1" group="1">  
4.         <name>张三</name>  
5.         <sex>男</sex>  
6.         <age>18</age>  
7.         <email>zhangsan@163.com</email>  
8.         <birthday>1987-06-08</birthday>  
9.         <memo>好学生</memo>  
10.     </student>  
11.     <student id="2" group="2">  
12.         <name>李四</name>  
13.         <sex>女</sex>  
14.         <age>18</age>

43. </root>  

Xml对应的实体bean文件:

 print?

1. package com.parsexml.entity;

16.     public void setId(int id) {  
17.         this.id = id;  
18.     }  
19.     public int getGroup() {

注：若工程中缺少kxml2-2.3.0.jar文件则会报以下异常信息:

你应该添加kxml2-2.3.0.jar包到你的classpath下
