java笔记:XPath的使用

// 使用XPath 获取name元素

    public static void test1() throws Exception{

        //1.创建解析器
        SAXReader saxReader = new SAXReader();

        //2.创建Document
        Document document = saxReader.read(PATH);

        //3.使用XPATH
        Node name = document.selectSingleNode("//p1[@id='abc']/name");

        //4.获取name的文本
        System.out.println(name.getText());

    }

//使用XPath 获取所有的name元素

    public static void AllName() throws Exception{
        //1.创建构造器
        SAXReader saxReader = new SAXReader();

        //2.获取Document
        Document document = saxReader.read(PATH);

        //3.获取所有的name
        List<Node> list = document.selectNodes("//name");

        //4.遍历获取所有值
        for (Node node : list){
            System.out.println(node.getText());
        }



    }
