解析C＃中的PayPal SOAP响应

问题描述：

如何解析此XML文件？我需要得到确认和标记值解析C＃中的PayPal SOAP响应

我已经试过

XmlDocument doc = new XmlDocument() 
doc.LoadXml(xml) 
XmlNode Ack = doc.DocumentElement.SelectSingleNode("//Ack") 
XmlNode Token = doc.DocumentElement.SelectSingleNode("//Token")

我的XML字符串是好的，下面，但确认和令牌为空。

如果您正在与肥皂服务交互，您可能需要添加服务引用并让它为您创建代理类。

使用LINQ到XML，你可以不喜欢下面

var parsedSoap = XElement.Parse(soapMessage); 
    XNamespace payPalResponseNs ="urn:ebay:api:PayPalAPI"; 
    XNamespace resultingResponseNs = "urn:ebay:apis:eBLBaseComponents"; 
    parsedSoap.Descendants() 
       .Where(x=> x.Name == payPalResponseNs+"SetExpressCheckoutResponse") 
       .Select(x=> new 
        { 
         Timestamp = x.Element(resultingResponseNs +"Timestamp")?.Value, 
         Ack = x.Element(resultingResponseNs +"Ack")?.Value, 
         CorrelationID = x.Element(resultingResponseNs +"CorrelationID")?.Value, 
         Version = x.Element(resultingResponseNs +"Version")?.Value, 
         Build = x.Element(resultingResponseNs +"Build")?.Value, 
         Token = x.Element(payPalResponseNs +"Token")?.Value 
        } 
        );

或更好，但

 XmlDocument doc = new XmlDocument(); 
 
     XmlNamespaceManager mgr = new XmlNamespaceManager(doc.NameTable); 
 
     mgr.AddNamespace("PayPalAPI", "urn:ebay:api:PayPalAPI"); 
 
     mgr.AddNamespace("eBLBaseComponents", "urn:ebay:apis:eBLBaseComponents"); 
 
     doc.LoadXml(xml); 
 
     XmlNode Ack = doc.SelectSingleNode("//eBLBaseComponents:Ack", mgr); 
 
     XmlNode node = doc.SelectSingleNode("//PayPalAPI:SetExpressCheckoutResponse", mgr); 
 
     
 
     string strAck = null; 
 
     if (Ack != null) 
 
      strAck = Ack.InnerText.ToLower(); 
 
     if (strAck != null && (strAck == "success" || strAck == "successwithwarning")) 
 
     { 
 
      //token = decoder["TOKEN"]; 
 
      foreach (XmlNode child in node.ChildNodes) 
 
      { 
 
       if (child.Name.ToLower() == "token") 
 
       { 
 
        token = child.InnerText; 
 
       } 
 
      } 
 
     }
