C# SQLXML 反序列化为类或对象

http://rtt.metroinfo.org.nz/RTT/Public/Utility/File.aspx?Name=JPRoutePositionET.xml&ContentType=SQLXML&PlatformTag=536

这两个都是我使用 HttpClient 拉下的示例数据，我想获取属性（？），例如 PlatformTag、ETA 等。

这是使用适用于 Windows 10 移动版和桌面版的通用应用程序。但我无法弄清楚这是怎么回事。

XDocument Document =  XDocument.Parse(RESPONSE_CONSTANT);
var Stops = from Stop in Document.Descendants("Platform")
select new
{
Platformtag = (string)Stop.Attribute("PlatformTag"),
Platformno = (string)Stop.Attribute("PlatformNo")};
foreach (var item in Stops)
BusData.Text = item.Platformtag;
}

是我目前拥有的，但没有任何东西来自它，它只是坐在那里就像什么也看不见，从这里我对 XML Parsing 的了解还不够，无法找到下一步。

注意：Response_Constant 包含这样的数据：http://rtt.metroinfo.org.nz/RTT/Public/Utility/File.aspx?Name=JPRoutePositionET.xml&ContentType=SQLXML&PlatformTag=536

尝试关注。不得不修改 xml 来替换 & 号。

namespace ConsoleApplication14

        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            string xml = File.ReadAllText(FILENAME);
            xml = xml.Replace("&", "&");
            StringReader sReader = new StringReader(xml);
            XmlReaderSettings settings = new XmlReaderSettings();
            settings.ConformanceLevel = ConformanceLevel.Fragment;
            XmlReader reader = XmlReader.Create(sReader);

            List<Platform> platforms = new List<Platform>();
            while (!reader.EOF)
            {
                if (reader.Name != "Platform")
                {
                    reader.ReadToFollowing("Platform");
                }
                if (!reader.EOF)
                {
                    XElement platform = (XElement)XElement.ReadFrom(reader);

                    platforms.Add(new Platform()

                    });
                }
