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() {
          return id;
      }
      public void setId(int id) {
          this.id = id;
      }
      public int getGroup() {
          return group;
      }
      public void setGroup(int group) {
          this.group = group;
      }
      public String getName() {
          return name;
      }
      public void setName(String name) {
          this.name = name;
      }
      public String getSex() {
          return sex;
      }
      public void setSex(String sex) {
          this.sex = sex;
      }
      public int getAge() {
          return age;
      }
      public void setAge(int age) {
          this.age = age;
      }
      public String getEmail() {
