如何解析这个XML文件?我需要获取Ack和Token值

I've try 

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

我的xml字符串如下所示，但Ack和Token为空。

在c#中解析PayPal SOAP响应

如果您正在与soap服务交互，您可能希望添加一个服务引用，并让它为您创建代理类。

使用Linq to XML你可以做如下的事情

    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
                    }
                    );

或者

        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;
                }
            }
        }
