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;
    }
 
}
