演示示例

这是我们需要创建的XML文档：

<?xml version="1.0" encoding="UTF-8"?>
<cars>
  <supercars company="Ferrari">
    <carname type="formula one">Ferrari 101</carname>
    <carname type="sports">Ferrari 202</carname>
  </supercars>
</cars>

 

演示示例：

CreateXmlFileDemo.java

package com.yiibai.xml;

import java.io.IOException;
import java.io.UnsupportedEncodingException;

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

public class DOM4JCreateXMLDemo {
   public static void main(String[] args) {
      try {
         Document document = DocumentHelper.createDocument();
         Element root = document.addElement( "cars" );
         Element supercarElement= root.addElement("supercars")
	        .addAttribute("company", "Ferrai");

         supercarElement.addElement("carname")
	        .addAttribute("type", "Ferrari 101")
	        .addText("Ferrari 101");

         supercarElement.addElement("carname")
            .addAttribute("type", "sports")
            .addText("Ferrari 202");

         // Pretty print the document to System.out
         OutputFormat format = OutputFormat.createPrettyPrint();
         XMLWriter writer;
         writer = new XMLWriter( System.out, format );
         writer.write( document );
      } catch (UnsupportedEncodingException e) {
         e.printStackTrace();
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

这将产生以下结果:

<?xml version="1.0" encoding="UTF-8"?>
<cars>
  <supercars company="Ferrari">
    <carname type="formula one">Ferrari 101</carname>
    <carname type="sports">Ferrari 202</carname>
  </supercars>
</cars>
