使用DOM4J创建XML

1、需要创建的XML文档resident.xml的内容如下：

<?xml version="1.0" encoding="utf-8"?><family><father nativeplace="湖北武汉">张三</father><wife nativeplace="浙江杭州">里斯</wife><son>张帆</son></family>

2、创建该文档的程序CreateXML.java

package dom4j.sample;import java.io.*;import org.dom4j.*;import org.dom4j.io.*;public class CreateXML {public static void main(String[] args) {createTestXML();}public static void createTestXML() {Document document = DocumentFactory.getInstance().createDocument();Element root = document.addElement("family");//<family>元素document.setRootElement(root); //设置为根元素Element father = root.addElement("father"); //子元素fatherElement wife = root.addElement("wife"); //子元素wifeElement son = root.addElement("son"); //子元素sonfather.addText("张三"); //设置元素值wife.addText("里斯");son.addText("张帆");father.addAttribute("nativeplace", "湖北武汉");//添加属性wife.addAttribute("nativeplace", "浙江杭州");try {XMLWriter writer = new XMLWriter(new FileOutputStream("resident.xml"),OutputFormat.createPrettyPrint());//创建格式化输出对象writer.write(document); //写文档 write.flush(); //将缓存数据写入磁盘writer.close(); //关闭XMLWriterSystem.out.println("创建完成！");} catch (IOException e) {e.printStackTrace(); }}}
