xml要素配列から値を取得するxmlシリアル化

Question

次の例のxmlがあります。xml要素の配列（ "READING"要素）から値を取得するためにXMLを逆シリアル化しようとしています。 22.9インチ以下（説明するのは難しい）です。

XmlSerializerを使用して他の値をすべて取得できます。

例のxml：

<LIVE deviceid="1394602" utc="18-Oct-2016 01:22:28" local="18-Oct-2016 12:22:28"> 
     <READINGS type="full" probecount="1" portcount="2" discovery="2"> 
      <READING parameter="Temperature" shortparameter="Temp" unit="°C" channel="1" probeid="3" state="OK" probename="EC202" sensor="0">22.9</READING> 
      <READING parameter="Ozone" shortparameter="O3" unit="ppm" channel="0" probeid="3" state="OK" probename="EC202" sensor="72">5</READING> 
     </READINGS> 
</LIVE> 

私は、このためにヘルプをしてくださいもらえますか？

おかげ

      </READING> 
     </READINGS> 
</LIVE>"; 
      var serializer = new XmlSerializer(typeof(LIVE)); 
      using(var reader = new StringReader(xml)) 
      { 
       var live = (LIVE)serializer.Deserialize(reader); 
       var output = default(double); 
       var text = Regex.Match(live.READINGS.READING.Text, @"\d+(\.\d+)?").Value; 
       if (double.TryParse(text, out output)) 
       { 
        Console.WriteLine(output); 
       } 
      } 
      Console.ReadLine();
