XML

如何将XML文档信息封装到对象中去？

首先我们要引入dom4j工具包

package gz.itcast.a_dom4j_read;

import java.io.File;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

/**

public class Demo4 {

		public static void main(String[] args) throws Exception{
			List<Contact> list = new ArrayList<Contact>();
			
			//读取xml，封装对象
			SAXReader reader = new SAXReader();
			Document doc = reader.read(new File("./src/contact.xml"));
			//读取contact标签
			Iterator<Element> it = doc.getRootElement().elementIterator("contact");
			while(it.hasNext()){
				Element elem = it.next();
				//创建Contact
				Contact contact = new Contact();
				contact.setId(elem.attributeValue("id"));
				contact.setName(elem.elementText("name"));
				contact.setAge(elem.elementText("age"));
				contact.setPhone(elem.elementText("phone"));
				contact.setEmail(elem.elementText("email"));
				contact.setQq(elem.elementText("qq"));
				list.add(contact);
			}
			
			for (Contact contact : list) {
				System.out.println(contact);
			}
			
			
		}
}
