我有這樣的一段XML從我的GPS設備和IM嘗試將其解析到一個列表中的軌道

public class track 
{ 
    public float positionx; 
    public float positiony; 
    public float altitude; 
    public DateTime Time; 
} 

已經沒有做太多的XML的工作，我一直在閱讀各種XML的方法，包括XPath和LinqToXML，但即時通訊掙扎解析XML，特別是「位置和其子值

我將是在這一個

這個S的任何幫助非常感謝應該訣竅：

XDocument doc = XDocument.Load("file.xml"); 

var tracks = (from elem in doc.Root.Descendants("Trackpoint") 
       select new track() 
       { 
        Time = DateTime.Parse(elem.Element("Time").Value, CultureInfo.InvariantCulture), 
        positionx = float.Parse(elem.Element("Positition").Element("LatitudeDegrees").Value, CultureInfo.InvariantCulture), 
        positiony = float.Parse(elem.Element("Positition").Element("LongitudeDegrees").Value, CultureInfo.InvariantCulture), 
        altitude = float.Parse(elem.Element("AltitudeMeters").Value, CultureInfo.InvariantCulture), 
       }); 

告訴我，如果它的工作！
