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>
