Read Soap Message using C#

Question

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Head>
    <h:talkId s:mustknow="1" xmlns:h="urn:schemas-test:testgate:hotel:2012-06">
      sfasfasfasfsfsf</h:talkId>
    </s:Head>
  <s:Body>
    <bookHotelResponse xmlns="urn:schemas-test:testgate:hotel:2012-06" xmlns:d="http://someURL" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
      <d:bookingReference>123456</d:bookingReference>
      <d:bookingStatus>successful</d:bookingStatus>
      <d:price xmlns:p="moreURL">
        <d:total>105</d:total>
      </d:price>
    </bookHotelResponse>
  </s:Body>
</s:Envelope>

I am trying to read the above soap message XmlDocument using C#:

XmlDocument document = new XmlDocument();
document.LoadXml(soapmessage);  //loading soap message as string
XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable);

manager.AddNamespace("d", "http://someURL");

XmlNodeList xnList = document.SelectNodes("//bookHotelResponse", manager);
int nodes = xnList.Count;

foreach (XmlNode xn in xnList)
{
    Status = xn["d:bookingStatus"].InnerText;
}

The count is always zero and it is not reading the bookingstatus values.

Answer 1

As I understand you want to get response from soap service. If so, you don't have to do all this hard work (making call, parsing xml, selecting nodes to get the response value) by yourself... instead you need to Add Service Reference to your project and it will do all the rest work for you, including generating class, making asmx call and so on... Read more about it here https://msdn.microsoft.com/en-us/library/bb628649.aspx

Everything you'll need to do after adding reference is to invoke a class method something like this

var latestRates = (new GateSoapClient())?.ExchangeRatesLatest();
return latestRates?.Rates;

Answer 2

First you want to create a class to deseralize the xml values into

    public class bookHotelResponse {
      public int bookingReference { get; set; }
      public int bookingStatus { get; set; }
   } 

Then you can utilize GetElementsByTagName to extract the body of the soap request and deseralize the request string into an object.

    private static T DeserializeInnerSoapObject<T>(string soapResponse)
    {
        XmlDocument xmlDocument = new XmlDocument();
        xmlDocument.LoadXml(soapResponse);

        var soapBody = xmlDocument.GetElementsByTagName("soap:Body")[0];
        string innerObject = soapBody.InnerXml;

        XmlSerializer deserializer = new XmlSerializer(typeof(T));

        using (StringReader reader = new StringReader(innerObject))
        {
            return (T)deserializer.Deserialize(reader);
        }
    }
