PULL解析XML

XML：

<?xml version="1.0" encoding="UTF-8"?>
<persons>
	<person id = "23">
		<name>张老师</name>
		<age>21</age>
	</person>
	<person id = "20">
		<name>李老师</name>
		<age>25</age>
	</person>

</persons>

Person类：

package com.pull.domain;

public class Person {

	private int id;
	private String name;
	private int age;

	public int getId() {
		return id;
	}

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

	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 Person() {
		// TODO Auto-generated constructor stub
	}

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

}

PullXMLTools类：

package com.pull.parser;

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

import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import org.xmlpull.v1.XmlPullParserFactory;

import com.pull.domain.Person;

/**
 * 主要是使用PULL解析xml
 * 
 * @author jack

 */
public class PullXMLTools {

	public PullXMLTools() {
		// TODO Auto-generated constructor stub
	}

	/**
	 * @param inputStream
	 *            从服务器获取xml文件，以流的形式返回
	 * @param encode
	 *            编码格式
	 * @return
	 * @throws Exception
	 */
	public static List<Person> parseXML(InputStream inputStream,String encode)
			throws Exception {
		List<Person> list = null;
		Person person = null;// 装载解析每一个person节点的内容
		// 创建一个xml解析的工厂
		XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
		// 获得xml解析类的引用
		XmlPullParser parser = factory.newPullParser();
		parser.setInput(inputStream,encode);
		// 获得事件的类型
		int eventType = parser.getEventType();
		while (eventType != XmlPullParser.END_DOCUMENT) {
			switch (eventType) {
			case XmlPullParser.START_DOCUMENT:
				list = new ArrayList<Person>();
				break;
			case XmlPullParser.START_TAG:
				if ("person".equals(parser.getName())) {
					person = new Person();
					// 取出属性值
					int id = Integer.parseInt(parser.getAttributeValue(0));
					person.setId(id);
				} else if ("name".equals(parser.getName())) {
					String name = parser.nextText();// 获取该节点的内容
					person.setName(name);
				} else if ("age".equals(parser.getName())) {
					int age = Integer.parseInt(parser.nextText());
					person.setAge(age);
				}
				break;
			case XmlPullParser.END_TAG:
				if ("person".equals(parser.getName())) {
					list.add(person);
					person = null;
				}
				break;
			}
			eventType = parser.next();
		}
		return list;
	}

}

Test类：

package com.pull.test;

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

import com.pull.domain.Person;
import com.pull.http.HttpUtils;
import com.pull.parser.PullXMLTools;

public class Test {

	public Test() {
		// TODO Auto-generated constructor stub
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String path = "http://192.168.1.125:8080/myhttp/person.xml";
		InputStream inputStream = HttpUtils.getXML(path);
		List<Person> list = null;
		try {
			list = PullXMLTools.parseXML(inputStream,"utf-8");
			for (Person person : list) {
				System.out.println(person.toString());
			}
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}
