Android Pull解析XML

在上文中介绍了使用sax方式解析xml，这里介绍下在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对应的实体bean文件

package com.parsexml.entity;

public class Student {
     
     private int id;
     private int group;
     private String name;
     private String sex;
     private int age;
     private String email;
     private String memo;
     private String birthday;
     public int getId() {
