將C＃LINQ中的國家氣象服務SOAP服務解析爲XML

我是一名初級C＃程序員，他正在嘗試開發一個庫，它允許我封裝解析從NWS返回的XML的討厭細節，並返回代表數據的集合。將C＃LINQ中的國家氣象服務SOAP服務解析爲XML

我的SOAP請求會以這種形式返回的XML文檔：

我試圖把最大值和最小值的臨時工是該XML字符串中的單獨集合內而忽略了「名」使用LINQ的元素。

編輯：這是我用它來從Web引用的XML代碼：

WeatherNWS.ndfdXML client = new TestNWS.WeatherNWS.ndfdXML(); 

    string XMLZip = client.LatLonListZipCode("48180"); 

    XElement myElement = XElement.Parse(XMLZip); 
    string[] myString = myElement.Value.Split(','); 

    decimal lat = Convert.ToDecimal(myString[0]); 
    decimal lon = Convert.ToDecimal(myString[1]); 

    weatherParametersType parameters = new weatherParametersType(); 

    parameters.maxt = true; 
    parameters.mint = true; 

    string XML = client.NDFDgen(lat, lon, productType.timeseries, DateTime.Now, DateTime.Now.AddDays(7), parameters);

嘿，我*剛剛完成*創建一個組件，可以一次完成多達500個經緯度對...如果我的作品不是專有的=（我會分享源代碼... – 2009-02-04 23:11:02

如果你僅僅使用一個數據點，你的問題就會容易得多 - 但是你需要記住不同的時間鍵，他們可以爲不同的時間參考mint和maxt，即使是相同的數據點，也取決於時間 – 2009-02-04 23:13:42

這應該是能夠得到的最高溫度爲你，你只需要改變的地方過濾器，以獲得最低

using System.Xml.Linq; 
\\... 

XDocument xmlDoc = XDocument.Load("YourXml.xml"); 
var maximums = from tempvalue in xmlDoc.Descendants("temperature").Elements("value") 
          where tempvalue.Parent.Attribute("type").Value == "maximum" 
          select (string)tempvalue; 

List<string> returnme = maximums.ToList<string>(); 
return returnme;

希望這有助於。

注意：我在C＃中使用Linq到Xml有點生疏，所以它可能不是最優雅的解決方案。

您可能會需要分析你回來使用XPath的XML拔出你想要的數據。有一個簡單的例子here。

或者，您可以創建一個反映xml結構並使用XmlSerializer將xml反序列化爲對象的類結構，但這可能比在此情況下值得的更麻煩。
