I don’t know if it meets the poster’s needs?

If the poster’s format is fixed, just parse it as aboveHTML会比较好一些，不需要REGEX.

String html = "<p id=\"AE9D7F630640426F8457A661607D2B8E-5-2\" style=\"display: none;\" class=\"kbcontent\">  19040172b-1  <br>SQL Server Develop  <br>  <font title=\"teacher\">zheng</font>  <br>  <font title=\"week\">3-5,7-14</font>  <br>  <font title=\"classroom\">D-101</font>  <br> </p> ";
        html = html.replaceAll("<br>", "#~#");
        Document doc = Jsoup.parse(html.toString());
        String newHtml = doc.text();
        String[] ary = newHtml.split("#~#");

        for (int i = 0;i < ary.length;i++){
            System.out.println(ary[i]);
        }

My needs are roughly like this
