, it will just not work:
Like:

C#

<pre
   IList<string> Regs = document.Descendants("Data").Select(GetFullPathtoKey).ToList();
        

      

         static string GetFullPathtoKey(XElement fileElement)
        {

           .Select(el => (string)el.Element("Contents"))
           .Reverse();
            return string.Join("\\", pathParts);
        }

<pre lang="text">

will give \\\\\\\\ for the first entry and
\\\\\\\Server for the second.


No I can create three lists for the path with Value, the Action and the Content, but that seems to be overkill.

After extracting the Path: "HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Features\8CD5D2FB0DBCDD64A8D2AB1D09CAF271\ClientPrograms"

how can I derive easily the Action, Type and the Content???

I have been piddling with this for the whole weekend without success. I guess I do not understand what the difference is
between the path to <value> and the path to .

Thanks a lot for any help!!!!
