Read Soap Message using C#

BookHotelResponse is in the namespace urn:schemas-test:testgate:hotel:2012-06 (the default namespace in the sample xml) so you need to provide that namespace in your queries:

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

manager.AddNamespace("d", "http://someURL"); 
manager.AddNamespace("bhr", "urn:schemas-test:testgate:hotel:2012-06"); 

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

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

Use LINQ2XML

To read bookingStatus,do this

XElement doc = XElement.Load("yourStream.xml");
XNamespace s = "http://schemas.xmlsoap.org/soap/envelope/";//Envelop namespace s
XNamespace bhr="urn:schemas-test:testgate:hotel:2012-06";//bookHotelResponse namespace
XNamespace d="http://someURL";//d namespace

foreach (var itm in doc.Descendants(s + "Body").Descendants(bhr+"bookHotelResponse"))
{
itm.Element(d+"bookingStatus").Value;//your bookingStatus value
}

LINQ2XML is cool though....:)

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);
        }
    }
