Using C# to parse a SOAP Response

Question

I am trying to get the values for faultcode, faultstring, and OrderNumber from the SOAP below

Answer 1

Yes, you're ignoring the XML namespace when selecting:

<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
   .....
   <m:SaveOrder xmlns:m="http://www.test.com/software/schema/" UserGUID="test">
     <Order OrderNumber="1234-1234-123" Caller="" OrderStatus="A" xmlns="http://www.test.com/software/schema/">

The <Order> tag is inside the <m:SaveOrder> tag which uses the XML namespace prefixed by the m: prefix.

Also, you're trying to select the "detail" and then you skip to the "Order" node directly (using .Elements()) - you missed the <m:SaveOrder> node in between.

You need to take that into account when selecting:

XDocument doc = XDocument.Load(HttpContext.Current.Server.MapPath("XMLexample.xml"));

XNamespace xmlns = "http://www.test.com/software/schema/";

var orderNode = doc.Descendants(xmlns + "SaveOrder").Elements(xmlns + "Order");

var value = from o in orderNode.Attributes("OrderNumber")
            select o.Value;

Does that give you a result??
