使用DOM4J来生成一个XML文件(一)

 首先,用Eclipse新建一个工程,然后导入dom4j-1.6.1.jar包,然后新一个类,代码如下:

 Dom4jTest.java

import org.dom4j.*;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;
import java.io.*;

public class Dom4jTest {

	public static void main(String args[]) {
		Document doc = DocumentHelper.createDocument();
		Element root = DocumentHelper.createElement("students");
		doc.setRootElement(root);
		
		Element stu1 = root.addElement("student");
		Element name = stu1.addElement("name");
		Element age = stu1.addElement("age");
		name.setText("张三");
		age.setText("23");
		
		Element stu2 = root.addElement("student");
		Element name2 = stu2.addElement("name");
		Element age2 = stu2.addElement("age");
		name2.setText("李四");
		age2.setText("24");
		try {
			//输出样式
			OutputFormat outFmt = new OutputFormat("    ", true);
			outFmt.setEncoding("GB2312");
			//输出xml文件
			XMLWriter xml = new XMLWriter(new FileWriter("F://test.xml"),outFmt);
			xml.write(doc);
			xml.flush();
		} catch (IOException e) {
			e.printStackTrace();
		}

	}
}

test.xml
