快捷方式:

  select:选择器

    使用的方法:Element select(String CssQuery)

      语法:参数selector类中定义语法

 

String path = JsoupDemo5.class.getClassLoader().getResource("student.xml").getPath();
        Document document = Jsoup.parse(new File(path), "utf-8");

        //查询name标签
        Elements name = document.select("name");
        System.out.println(name);

        //查询id值为example
        Elements select = document.select("#example");
        System.out.println(select);

        Elements select1 = document.select("studnet[number=\"heima_0001\"]");
        System.out.println(select1);

        Elements select2 = document.select("studnet[number=\"heima_0001\"] > age");
        System.out.println(select2);

 

 

 

 

 

 

 

 

 

 

 

 

 

 

xml_解析_jsoup根据Xpath查询

Xpath:Xpath及为XMl路径语言,他是一种用来确定XmL(标准通用标记语言的子集)文档中某部分位置的语言

  使用Jsoup的Xpath需求额导入jar包

  查询w3school参考手册,使用xapth的语法完成查询

    public static void main(String[] args) throws IOException {

        String path = JsoupDemo6.class.getClassLoader().getResource("student.xml").getPath();
        Document document = Jsoup.parse(new File(path), "utf-8");
        JXDocument jxDocument = new JXDocument(document);
        List<JXNode> jxNodes = jxDocument.selN("//student");
        for (JXNode jxNode: jxNodes) {
            System.out.println(jxNode);
        }

        List<JXNode> jxNodes2 = jxDocument.selN("//student/name");
        for (JXNode jxNode: jxNodes2) {
            System.out.println(jxNode);
        }

        List<JXNode> jxNodes3= jxDocument.selN("//student/name[@id]");
        for (JXNode jxNode: jxNodes3) {
            System.out.println(jxNode);
        }


        List<JXNode> jxNodes4 = jxDocument.selN("//student/name[@id='example']");
        for (JXNode jxNode: jxNodes4) {
            System.out.println(jxNode);
