解析xml文件有很多方法，有SAX，还有DOM,在android中，android自带了XmlPullParse相关包，

在android中要解析xml文件，推荐使用XmlPullParse解析。

下面是一个使用的相关案例:

PersonService:

package com.example.service;import java.io.InputStream;import java.util.ArrayList;import java.util.List;import org.xmlpull.v1.XmlPullParser;import android.content.Intent;import android.util.Xml;import com.example.domain.Person;public class PersonService {public static List<Person> getPersons(InputStream xml) throws Exception{List<Person> persons = null;Person person = null;XmlPullParser pullParser = Xml.newPullParser();pullParser.setInput(xml, "UTF-8");int event = pullParser.getEventType();while(event != XmlPullParser.END_DOCUMENT){switch (event) {case XmlPullParser.START_DOCUMENT:persons = new ArrayList<Person>();break;case XmlPullParser.START_TAG:if("person".equals(pullParser.getName())){person = new Person();//这是获得字段的属性int id = new Integer(pullParser.getAttributeValue(0));person.setId(id);}if("name".equals(pullParser.getName())){//获得其中的内容String name = pullParser.nextText();person.setName(name);}if("age".equals(pullParser.getName())){int age = new Integer(pullParser.nextText());person.setAge(age);}break;case XmlPullParser.END_TAG:if("person".equals(pullParser.getName())){persons.add(person);person = null;}break;default:break;}event = pullParser.next();}return persons;}}

将xml文件放在类路径目录下，编写测试案例:

package cn.example.test;import java.io.InputStream;import java.util.List;import android.test.AndroidTestCase;import android.util.Log;import com.example.domain.Person;import com.example.service.PersonService;public class PersonServiceTest extends AndroidTestCase {public void testPersonXml() throws Exception{InputStream xml = this.getClass().getClassLoader().getResourceAsStream("person.xml");List<Person> persons = PersonService.getPersons(xml);for(Person person:persons){Log.d("TAG", person.toString());}}}

xml文件:

<?xml version="1.0" encoding="utf-8"?><Persons>    <person id="1">        <name>zhangsan</name>        <age>12</age>    </person>    <person id="2">        <name>lisi</name>        <age>22</age>    </person></Persons>

测试结果：

12-26 07:15:45.022: D/TAG(10150): Person [id=1, name=zhangsan, age=12]

12-26 07:15:45.022: D/TAG(10150): Person [id=2, name=lisi, age=22]
