用Dom4J解析即编写xml

Dom4J小程序1.
package WildCat.Xml.Dom4j;

import java.io.FileOutputStream;
import java.io.IOException;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;

public class Dom4J1_1 {

	/**
	 * @param args
	 * @throws IOException 
	 */
	public static void main(String[] args) throws IOException {
//		//创建文档  第一种方式
//		Document document=DocumentHelper.createDocument();
//		//创建根元素节点
//		Element root=DocumentHelper.createElement("企业名单");
//		document.setRootElement(root);
		
		//创建文档的第二种方式
		Element root=DocumentHelper.createElement("企业名单");
		
		Document document=DocumentHelper.createDocument(root);
		root.addAttribute("地区", "华北");
		Element name=root.addElement("名字");
		Element address=root.addElement("地址");
		Element tel=root.addElement("电话");
		name.addText("WildCat科技有限公司");
		address.addText("烟台");
		tel.addText("18253576788");
		//输出到命令行
		XMLWriter writer=new XMLWriter();
		
		writer.write(document);
		//输入硬盘
		OutputFormat format=new OutputFormat("  ",true);
		
		XMLWriter writer2=new XMLWriter(new FileOutputStream("企业名单.xml"),format);
		
		writer2.write(document);
		
		
		
		

	}

}
小程序2：
package WildCat.Xml.Dom4j;

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

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

public class Dom4JTest1_2 {

	/**
	 * @param args
	 * 
	 * 通过DOM4J读取XML
	 * @throws DocumentException 
	 */
	public static void main(String[] args) throws DocumentException {
		//
		SAXReader reader=new SAXReader();
		Document document=reader.read(new File("企业名单.xml"));
		Element root=document.getRootElement();
		System.out.println(root.getName());
		//List ChildList=root.elements();
		System.out.println(root.attributeValue("地区"));
		for (Iterator iter=root.elementIterator();iter.hasNext();)
		{
			Element e=(Element)iter.next();
			System.out.println(e.getName()+":"+e.getStringValue());
			
			
		}
		
		
		
	}
