                    fxfv = feed.Attribute("SharepointGroup").Value
                };

I think you have a mistake in where condition, see below:

feed.Attribute("id") returns XAttribute class so you can't use equals to compare to a string, but after Value property you can.

        var feeds = from feed in xDoc.Descendants("name")
                    where feed.Attribute("id").Value.Equals("Test1")
                    select new
                    {
                        fxfv = feed.Attribute("SharepointGroup").Value
                    };
