xmlpull解析也是跟sax解析一样，都是边解析边释放，所以不会像dom解析那样出现出现溢出。

他的实现代码如下：

package itcast.cn;


import java.io.FileInputStream;

import java.util.ArrayList;


import org.xmlpull.v1.XmlPullParser;

import org.xmlpull.v1.XmlPullParserException;

import org.xmlpull.v1.XmlPullParserFactory;

//把两个person封装到集合里面

//则需要有两个对象，然后把数据放在对象里面，之后把对象放在集合里面

public class Pull {


public static void main(String[] args) throws Exception {

//必须要导入家暴--由于是第三方的，所以要导入

XmlPullParserFactory factory = XmlPullParserFactory.newInstance();

XmlPullParser pullParser = factory.newPullParser();

//解析文件

pullParser.setInput(new FileInputStream("person.xml"), "utf-8");

//获取事件类型

int type=pullParser.getEventType();

   //循环移动解析器

Person person=null;

ArrayList<Person> persons =null;

while(type!=XmlPullParser.END_DOCUMENT){

switch(type){

case XmlPullParser.START_TAG:

if (pullParser.getName().equals("persons")) {

persons = new ArrayList<Person>();

}else if (pullParser.getName().equals("person")) {

person=new Person();

String id = pullParser.getAttributeValue(0);

person.setId(id);

}else if (pullParser.getName().equals("name")) {

//拿到下一个的值

String name= pullParser.nextText();

person.setName(name);

}else if (pullParser.getName().equals("age")) {

String age= pullParser.nextText();

//由于得到的是String类型，所以需要将这个String类型的转换成int

person.setAge(Integer.parseInt(age));

}

break;

case XmlPullParser.END_TAG:

if (pullParser.getName().equals("person")) {

persons.add(person);

}

break;

default:

break;

 

}

type=pullParser.next();

 }

System.out.println(persons);

}


}

Person对象：

package itcast.cn;


public class Person {

private String name;

private int age;

private String id;


public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}


@Override

public String toString() {

return "Person [name=" + name + ", age=" + age + ", id=" + id + "]";

}


public Person(String id, String name, int age) {

super();

this.id = id;

this.name = name;

this.age = age;

}


public Person() {

super();

// TODO Auto-generated constructor stub

}



}
