在页面中显示 xml 代码

Question

我正在尝试以 xml 格式生成 API who returns 信息。使用正确的 URL 时，可以正确生成 Xml 文档，但我无法显示它并将其发回。例如，在 http://maps.googleapis.com/ 中，如果我 select 一个地方，我会得到信息，并且我可以在浏览器中的一个漂亮的 XML 文档中看到它。

这正是我想要做的。

以下是我创建 xml 的方式：

                    XmlDocument XmlDoc = new XmlDocument();
        XmlDeclaration XmlDecl;
        XmlDecl = XmlDoc.CreateXmlDeclaration("1.0", "UTF-8", "");
        XmlDoc.AppendChild(XmlDecl);

        XmlElement RootElem = XmlDoc.CreateElement("cars");
        XmlDoc.AppendChild(RootElem);

        if (result.Count > 0)
        {
            XmlElement xmlCar;
            XmlElement xmlElem;
            XmlElement xmlSubElem;
            foreach (VehiculoResult item in result)
            {
                if (!(int.Parse(driver_age) < 21 && item.TipoSeguro == 2))
                {
                    string accris = CreateAccriscode(item);
                    xmlCar = XmlDoc.CreateElement("car");
                    RootElem.AppendChild(xmlCar);
                    xmlElem = XmlDoc.CreateElement("Acrisscode");
                    xmlElem.InnerText = accris;
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("Description");
                    xmlElem.InnerText = "<![CDATA[" + item.Descripcion + "]]>";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("Capacity");
                    xmlElem.InnerText = item.NumPlazas.ToString();
                    xmlCar.AppendChild(xmlElem);
                    DateTime fechaInicio = DateTime.Parse(pickup_date + " " + pickup_time);
                    DateTime fechaFin = DateTime.Parse(dropoff_date + " " + dropoff_time);
                    double price = UtilesReserva.ObtenerImporteReserva(TimeSpan.Parse((fechaFin - fechaInicio).ToString()),
                                                         item.PrecioHora, item.PrecioDia,
                                                         item.PrecioSemana, item.PrecioMes);
                    if (item.TipoSeguro == 2)
                    {
                        price += wService.CalcularPrecioSeguro(fechaInicio, fechaFin);
                    }
                    xmlElem = XmlDoc.CreateElement("Price");
                    xmlElem.InnerText = price.ToString();
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("IncludedDistance");
                    if (item.LimitacionKM == 1)
                    {
                        xmlElem.InnerText = "250";
                    }
                    else if (item.LimitacionKM == 2)
                    {
                        xmlElem.InnerText = "500";
                    }
                    else
                    {
                        xmlElem.InnerText = "0";
                    }
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("IncludedDistanceUnit");
                    xmlElem.InnerText = "K";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("IncludedDistanceType");
                    xmlElem.InnerText = "D";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("ExtraDistancePrice");
                    xmlElem.InnerText = "0.15";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("AptTax");
                    xmlElem.InnerText = "0";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("AppTaxIncluded");
                    xmlElem.InnerText = "U";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("YoungDrvFee");
                    xmlElem.InnerText = "0";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("YoungDrvFeeIncluded");
                    xmlElem.InnerText = "Y";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("FuelPolicy");
                    xmlElem.InnerText = "U";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("Supplier");
                    xmlElem.InnerText = "Social Car";
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("Pickup");
                    xmlSubElem = XmlDoc.CreateElement("Address");
                    xmlSubElem.InnerText = "<![CDATA[" + item.Direccion + "]]>";
                    xmlElem.AppendChild(xmlSubElem);
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("Dropoff");
                    xmlSubElem = XmlDoc.CreateElement("Address");
                    xmlSubElem.InnerText = "<![CDATA[" + item.Direccion + "]]>";
                    xmlElem.AppendChild(xmlSubElem);
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("Image");
                    xmlElem.InnerText = item.UrlFotoPerfil;
                    xmlCar.AppendChild(xmlElem);
                    xmlElem = XmlDoc.CreateElement("Deep_link");
                    xmlElem.InnerText = "<![CDATA[" + item.Direccion + "]]>";
                    xmlCar.AppendChild(xmlElem);
                }
            }
        }

生成 Xml 文档后，我尝试使用以下方法：

        Response.ContentType = "text/xml"; //must be 'text/xml'
        Response.ContentEncoding = System.Text.Encoding.UTF8; //we'd like UTF-8
        XmlDoc.Save(Response.Output);

还有以下内容：

        var stringWriter = new StringWriter();
        var xmlTextWriter = XmlWriter.Create(stringWriter);
        XmlDoc.WriteTo(xmlTextWriter);
        xmlTextWriter.Flush();
        string result = stringWriter.GetStringBuilder().ToString();
        saveText.Text = result; //saveText is the ID of a Label

只显示我放入 InnerText 的值，但不会显示所有 xml 代码，我想让所有内容都显示出来。有人知道我遗漏了什么或做错了什么吗？

看多了终于找到了解决办法，就一行代码：

saveText.Text = Server.HtmlEncode(XmlDoc.InnerXml);

希望对大家有所帮助！
