public class JDOMParseXML {
    //解析XML
    	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){
    				System.out.println("name="+e.getChildText("name"));
    				System.out.println("sex="+e.getChildText("sex"));
    				System.out.println("email="+e.getChildText("email"));
