Answer 1

var result = doc.Descendants("TransactionInformationType");

selects all descendants in the XDocument that have element name "TransactionInformationType" and are in the empty namespace. From you screenshot it seems the element you're trying to select is in the namespace "https://ssl.ditonlinebetalingssystem.dk/remote/payment" though. You need to specify that explicitly:

XNamespace ns = "https://ssl.ditonlinebetalingssystem.dk/remote/payment";
                                              ↑↑                      ↑
var result = doc.Descendants(ns + "TransactionInformationType");

Answer 2

This should solve you isssue (replace the namespace with the right URL):

XNamespace ns = "https://ssl.ditonline...";
doc.Descendants(ns + "TransactionInformationType");
