Jdom生成xml文件

public static void updateXML(String filePath) throws Exception {
		SAXBuilder sb = new SAXBuilder();
		Document doc = sb.build(new FileInputStream(filePath));//读入文件
		Element root = doc.getRootElement(); //得到根元素
//		Element e = root.getChild("occupation");
//		System.out.println(e.getText());
//		System.out.println(e.getName());
//		System.out.println(e.getAttributeValue("dynasty"));//获取元素属性值
		
//		e.setText("大皇帝");
		
		List li = root.getContent();//全部内容：子元素、注释、文本等
		List list = root.getChildren(); //只有标记内容
		System.out.println(li.size());
		System.out.println(list.size());
		
		Element ele = (Element) list.get(0);
		System.out.println(ele.getText());
		//将doc写入到某一个xml文件中，从而更新硬盘中的文件
//		XMLOutputter xmlOut = new XMLOutputter();
//		xmlOut.output(doc, new FileOutputStream(filePath));
	}

//须要导入jdom.jar包
public static void createXML() throws Exception {
		Element root = new Element("resume");

		occupation.setAttribute(attr);

		preName.addContent("秦王");
		preOccupation.addContent("将军");
		occupation.addContent("皇帝");
		
		root.addContent(name);
		root.addContent(preName);
		root.addContent(occupation);
		root.addContent(preOccupation);

		Format format = Format.getPrettyFormat();
