Java 如何从JSP返回XML数据？

我必须从jsp页面返回xml数据

我从数据库中获取一条记录并显示在Jsp中。我必须返回xml格式的显示记录。我必须用jsp显示，同时用xml返回一条记录

我已经完成了一个显示过程，并以xml格式返回：

        String selectsql = null;
    DBConnection DBCon = null;
    Connection Con = null;      
    String maprule = null;
        PreparedStatement pstm = null;
        ResultSet resultSet = null;
        String snomedid = request.getParameter("snomedcode");
        String snomedname = request.getParameter("snomednames");

        try {
            DBCon = new DBConnection();
            Con = DBCon.getConnection();
            selectsql = "SELECT referencedComponentId,sctName,mapTarget,icdName,mapRule,refid FROM snomedicd10map WHERE referencedComponentId=? or sctName=? ";
            pstm = Con.prepareStatement(selectsql);
            pstm.setString(1, snomedid);
            pstm.setString(2, snomedname);
            resultSet = pstm.executeQuery();

如何实施？我需要再创建一个页面或在同一页面中创建一个页面。

您只需返回XML文本，而不是从JSP返回HTML文本

提供的代码具有HTML标记和JSP代码，用于创建HTML文档结构和内容

JSP的XML版本将包含XML标记和JSP代码，用于创建XML文档结构和内容。

是的，我使用XML标记，但我无法在前端UI中显示，因此，如果要在浏览器中显示XML数据，该怎么办，通常的方法是创建一个CSS样式表，告诉浏览器如何显示每个XML元素。你的拼写很糟糕，我真不敢相信你在小学就没有学过以大写字母开头的句子。
