Answer 1

使用XML解析XMLDocument，获取属性值和子属性值，然后将它们设置在您想要的某个div或任何其他标记内。我已经创建了一个测试代码，可以完美地解决您的问题：

        XmlDocument xmldoc = new XmlDocument();
        xmldoc.Load(xmlFile);//Load your xmlFile, put path here or xml string
        XmlNodeList nodeList = xmldoc.GetElementsByTagName("Promo");//get all the nodes of Promo
        var nodeX = nodeList.Cast<XmlNode>().
                    Select(x => new
                    {
                        Id = (string)x.Attributes["Id"].Value,
                        from = (string)x.Attributes["from"].Value,
                        to = (string)x.Attributes["to"].Value,
                        value = (string)x.ChildNodes[0].Attributes["value"].Value,
                        promokey = (string)x.ChildNodes[0].Attributes["promokey"].Value
                    });
        foreach (var item in nodeX)
        {   
            //Creating different tags and setting values
            HtmlGenericControl mainDiv = new HtmlGenericControl();
            mainDiv.TagName = "div";

            HtmlGenericControl id = new HtmlGenericControl();
            id.TagName = "h1";
            id.InnerText = item.Id;
            mainDiv.Controls.Add(id);


            HtmlGenericControl from = new HtmlGenericControl();
            from.TagName = "h4";
            from.InnerText = "From: " + item.from;
            mainDiv.Controls.Add(from);

            HtmlGenericControl to = new HtmlGenericControl();
            to.TagName = "h4";
            to.InnerText = "To: " + item.to;
            mainDiv.Controls.Add(to);

            HtmlGenericControl promokey = new HtmlGenericControl();
            promokey.TagName = "h4";
            promokey.InnerText = "promokey: " + item.promokey;
            mainDiv.Controls.Add(promokey);

            HtmlGenericControl value = new HtmlGenericControl();
            value.TagName = "h4";
            value.InnerText = "value: " + item.value;
            mainDiv.Controls.Add(value);

            Panel1.Controls.Add(mainDiv);//Adding all the tags within an asp.net panel
        }

在.aspx方面，我刚刚添加了一个这样的面板：

<asp:Panel ID="Panel1" runat="server"></asp:Panel>

此代码的输出是

希望它有所帮助！
