获取xml中节点

// 1.获取解析器
        SAXReader sax =new SAXReader();
        //2.获得docunment文档对象
        Document doc =sax.read("src/demo03/schema.xml");
        //3.获得根元素
        Element root =doc.getRootElement();        
        //System.out.println(root.getName());
        System.out.println(root.attributeValue("version"));
        //4.获取根元素下的子元素
        List<Element> list =root.elements();
        //5.遍历
        for(Element e:list){
            if("servlet".equals(e.getName())){
                Element servletname =e.element("servlet-name");
                Element servletclass =e.element("servlet-class");
                System.out.println(servletname+"\n"+servletclass);
                System.out.println(servletclass.getText());
            }
        }
