Linqtoxml, I cant seem to grab any elements in my document

Question

I have the following XML file, its SCORM for learning management system and I am having real problems with it.

<?xml version="1.0" encoding="utf-8" ?>

    </resource>
</resources>

My first problem is that I cant seem to get hold of any of the elements. I have tried a few methods but would like to use linqtoxml if possible.

I have tried the code below :

   XDocument xdoc = XDocument.Load(@"C:\Users\Stephen Liversidge\Desktop\SCORM Examples\1.2\cookies\unzipped\imsmanifest.xml");

        var lv1s = from docEls in xdoc.Root.Elements("manifest")
                   select docEls;

I am having no joy though, no matter what element I try to attach too, I get an enumeration yeilded no results method.

I have a feeling this is an easy one, but I am struggling to get a start point.

Could you help please.

thanks

Stephen
