使用pull方式解析xml文件示例：

网上的示例太多，基本类似，个人在此做个简单的总结：

1、首先在工程的asserts目录下建一个book.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

<books>

    <book id="1">

        <name>thinking in java</name>

        <price>85.5</price>

    </book>

    <book id="2">

        <name>Spring in Action</name>

        <price>39.0</price>

    </book>

</books>

2、创建Book.java类

/**

 * 

 */

package com.hyzhou.pulldemo;



/**

 * @author hyzhou

 * 

 *         2013-10-17

 */

public class Book {



    private int id;

    private String name;

    private float price;



    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 float getPrice() {

        return price;

    }



    public void setPrice(float price) {

        this.price = price;

    }



    @Override

    public String toString() {

        return this.id + ":" + this.name + ":" + this.price;

    }





}

3、创建PullParse.java类

/**

 * 

 */

package com.hyzhou.pulldemo;



import java.io.InputStream;

import java.util.ArrayList;

import java.util.List;



import org.xmlpull.v1.XmlPullParser;





import android.util.Xml;

/**

 * @author hyzhou

 *

 * 2013-10-17

 */

public class PullParse {



    public static List<Book> getBooks(InputStream inputStream) throws Exception

    {

        XmlPullParser parser=Xml.newPullParser();

        List<Book> books=null;

        Book book=null;

        parser.setInput(inputStream, "UTF-8");//以流的形式将xml文件载入

        

        int event=parser.getEventType();//产生第一个事件

        

        while (event != XmlPullParser.END_DOCUMENT) {

            switch (event) {

            case XmlPullParser.START_DOCUMENT://判断当前事件是否是文档开始事件 

                books=new ArrayList<Book>();//初始化books集合

                break;

            case XmlPullParser.START_TAG: //判断当前事件是否是标签元素开始事件  

                if ("book".equals(parser.getName())) {//判断开始标签元素是否是book   

                    book = new Book();

                    book.setId(Integer.parseInt(parser.getAttributeValue(0)));//得到book标签的属性值，并设置book的id   



                }

                else if ("name".equals(parser.getName())) {

                    book.setName(parser.nextText());

                }

                else if ("price".equals(parser.getName())) {

                    book.setPrice(Float.parseFloat(parser.nextText()));

                }

                /**

                if (book!=null) {

                    

                    if("name".equals(parser.getName())) //判断开始标签元素是否是name   

                    {    //判断开始标签元素是否是name

                        book.setName(parser.nextText());

                    }else if("price".equals(parser.getName())){//判断开始标签元素是否是price

                        book.setPrice(Float.parseFloat(parser.nextText()));

                    }

                }

                **/

                break;                

            case XmlPullParser.END_TAG:

                 if("book".equals(parser.getName())){//判断结束标签元素是否是book

                        books.add(book);//将book添加到books集合

                        book = null;

                    }

                 break;

            }

            

             event=parser.next();//进入下一个元素并触发相应事件   

        }

        return books;        

    }

}

4、编写MainActivity.java类

package com.hyzhou.pulldemo;



import java.io.InputStream;

import java.util.List;



import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.widget.TextView;

import android.widget.Toast;



public class MainActivity extends Activity {



    private TextView tView;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        tView = (TextView) findViewById(R.id.tv);

        try {

            //用类加载器加载xml文件，book.xml放在了assets文件下

            InputStream inputStream=getResources().getAssets().open("book.xml");

            List<Book> books = PullParse.getBooks(inputStream);



            StringBuffer sb = new StringBuffer();



            for (Book book : books) {

                String str = book.toString();

                sb.append(str);

                sb.append("\n");

            }

            tView.setText(sb.toString());

        } catch (Exception e) {

            // TODO: handle exception

            e.printStackTrace();

            Toast.makeText(this, "解析失败", Toast.LENGTH_LONG).show();

        }

    }



    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.

        getMenuInflater().inflate(R.menu.activity_main, menu);

        return true;

    }



}
