I’ve been trying to use Linq to XML to retrieve, say, the list of all StpLineType nodes.
I’ve tried doing so with something like:

XDocument xdoc = XDocument.Load(new StringReader(soapResponse));
var results = xdoc.Descendants("StpLineType");

But nothing is returned. I can see that the document is loaded into xdoc, but I can’t seem to correctly query it. FWIW, I’ve also tried:

XDocument xdoc = XDocument.Load(new StringReader(soapResponse));
XNamespace ns = "soap";
var results = xdoc.Descendants(ns + "StpLineType");

Just in case the namespace was causing the problem – no luck.

What am I missing?

    You’re ignoring the two XML namespaces on this document!

    • The root level and the <body> tag are in the soap namespace
    • the rest of the document is in the “default” namespace (without prefix) defined on the <PMWSGetReportResponse> element

    If you take that into account – things begin to work just fine!

    XDocument xdoc = XDocument.Load(new StringReader(soapResponse));

XNamespace soap = "http://schemas.xmlsoap.org/soap/envelope/";
XNamespace ns = "http://localhost/PCMilerWS/";

var results = xdoc.Root.Element(soap + "Body").Descendants(ns + "StpLineType");

    But the main question really is: why on earth are you manually parsing a SOAP response?? …..
