//创建文档

Document document = new Document();

//创建根元素

Element people = new Element("people");

//把根元素加入到document中

document.addContent(people);

//创建注释

Comment rootComment = new Comment("将数据从程序输出到XML中！");

people.addContent(rootComment);

//创建父元素

Element person1 = new Element("person");

//把元素加入到根元素中

people.addContent(person1);

//设置person1元素属性

person1.setAttribute("id", "001");

Attribute person1_gender = new Attribute("gender", "male");

person1.setAttribute(person1_gender);

Element person1_name = new Element("name");

person1_name.setText("刘德华");

person1.addContent(person1_name);

Element person1_address = new Element("address");

person1_address.setText("香港");

person1.addContent(person1_address);

Element person2 = new Element("person");

people.addContent(person2);

person2.setAttribute("id", "002").setAttribute("gender","male");//添加属性，可以一次添加多个属性

Element person2_name = new Element("name");

person2_name.setText("林志颖");

person2.addContent(person2_name);

Element person2_address = new Element("address");

person2_address.setText("台湾");

person2.addContent(person2_address);

//设置xml输出格式

Format format = Format.getPrettyFormat();

format.setEncoding("utf-8");//设置编码

format.setIndent("    ");//设置缩进

//得到xml输出流

XMLOutputter out = new XMLOutputter(format);

//把数据输出到xml中

out.output(document, new FileOutputStream("jdom.xml"));//或者FileWriter

}

}
