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:

<?xml version="1.0" encoding="UTF-8"?><root>    <student id="1" group="1">        <name>张三</name>        <sex>男</sex>        <age>18</age>        <email>[e-mail]</email>        <birthday>1987-06-08</birthday>        <memo>好学生</memo>    </student>    <student id="2" group="2">        <name>李四</name>        <sex>女</sex>        <age>18</age>        <email>[e-mail]</email>        <birthday>1987-06-08</birthday>        <memo>好学生</memo>    </student>    <student id="3" group="3">        <name>小王</name>        <sex>男</sex>        <age>18</age>        <email>[e-mail]</email>        <birthday>1987-06-08</birthday>        <memo>好学生</memo>    </student>    <student id="4" group="4">        <name>小张</name>        <sex>男</sex>        <age>18</age>        <email>[e-mail]</email>        <birthday>1987-06-08</birthday>        <memo>好学生</memo>    </student>    <student id="5" group="5">        <name>小明</name>        <sex>男</sex>        <age>18</age>        <email>[e-mail]</email>        <birthday>1987-06-08</birthday>        <memo>好学生</memo>    </student></root>

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() {        return email;    }    public void setEmail(String email) {        this.email = email;    }    public String getMemo() {        return memo;    }    public void setMemo(String memo) {        this.memo = memo;    }    public String getBirthday() {        return birthday;    }    public void setBirthday(String birthday) {        this.birthday = birthday;    }    }

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
