XDocument.Descendants not returning descendants

Answer 1

It is correct that you have to include the namespace, but the samples above do not work unless you put the namespace in curly braces:

XNameSpace ns = "http://www.lge.com/ddc";

foreach (XElement element in xdoc.Descendants("{" + ns + "}nationalList")
{
      MessageBox.Show(element.ToString());
}

You have to use the namespace:

// do _not_ use   var ns = ... here.
XNameSpace ns = "http://www.lge.com/ddc";

foreach (XElement element in xdoc.Descendants(ns + "nationalList")
{
      MessageBox.Show(element.ToString());
}

Answer 3

If you don't want to have to use the ns prefix in all the selectors you can also remove the namespace upfront when parsing the xml. eg:

string ns = "http://www.lge.com/ddc";
XDocument xdoc = XDocument.Parse(xml.Replace(ns, string.Empty));

foreach (XElement element in xdoc.Descendants("nationalList")
...

Answer 4

You're not including the namespace, which is "http://www.lge.com/ddc", defaulted from the parent element:

XNamespace ns = "http://www.lge.com/ddc";
foreach (XElement element in xdoc.Descendants(ns + "nationalList"))
{
    ...
}
