public class JDOMParseXML {

    	public static void main(String[] args) {
    		
    		SAXBuilder builder = new SAXBuilder();
    		
    		    //解析文件，指定文件位置；
    			Document document = builder.build("person.xml");
    			
    			//获得根节点
    			Element root = document.getRootElement();
    			//将获取到的根节点放入到集合中去
    			List<Element> list = root.getChildren();
    			for(Element e:list){
