Android XML解析之Pull

Pull解析XML文档；

首先建一个android项目，在cn.class3g.service里建一个名为person_list,xml：

<?xml version="1.0" encoding="UTF-8"?>
<persons>
    <person id="111">
        <name>Tom</name>
        <age>20</age>
    </person>
    <person id="222">
        <name>Mary</name>
        <age>17</age>
    </person>
</persons>
<?xml version="1.0" encoding="UTF-8"?>
<persons>
<person id="111">
  <name>Tom</name>
  <age>20</age>
</person>
<person id="222">
  <name>Mary</name>
  <age>17</age>
</person>
</persons>

在cn.class3g.domain包下封装javabean，person：

package cn.class3g.domain;

public class Person {
    private int id;
    private String name;
    private int age;

    public Person() {
    }

    public Person(int id, String name, int age) {
        super();
        this.id = id;
        this.name = name;
        this.age = age;
    }

    public int getId() {
        return id;
    }

    public void setId(int 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;
    }

    public String toString() {
        return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
    }

}
package cn.class3g.domain;

public class Person {
private int id;
private String name;
private int age;

public Person() {
}

public Person(int id, String name, int age) {
  super();
  this.id = id;
  this.name = name;
  this.age = age;
}

public int getId() {
return id;
}

public void setId(int 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;
}

public String toString() {
return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
}

}

在service包下创建PersonHandler类

<pre name="code" class="html">package cn.class3g.service;

import java.io.InputStream;
import java.io.Writer;
import java.util.ArrayList;
import java.util.List;

import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlSerializer;

import android.util.Xml;

import cn.class3g.domain.Person;

public class PullPersonService {

    public static List<Person> getPersonList(InputStream inStream)
            throws Exception {
        List<Person> personList = null;
        //拿到XmlPullParser解析器
        XmlPullParser parser = Xml.newPullParser();
        //统一编码
        parser.setInput(inStream, "utf-8");

        int eventType = parser.getEventType();
        //创建一个person对象
        Person person = null;
        //开始解析
        while (eventType != XmlPullParser.END_DOCUMENT) {
            switch (eventType) {
            case XmlPullParser.START_DOCUMENT:
                personList = new ArrayList<Person>();
                break;
            case XmlPullParser.START_TAG:
                // 判断当前元素名是否为person
                if ("person".equals(parser.getName())) {
                    person = new Person();
                    person.setId(Integer.valueOf(parser.getAttributeValue(0)));
                } else if ("name".equals(parser.getName())) {
                    person.setName(parser.nextText());
                } else if ("age
