LINQ query to parse content from XML to class

Question

I have an xml from which I am trying to extract some information through LINQ query.
The format of the xml file looks like the following:

Answer 1

var xDoc = XDocument.Load(....);
var result = xDoc.Descendants("NextItem")
  .Union(xDoc.Descendants("PreviousItem"))
  .Select(n => new {ID = n.Attribute("id").Value, Name =n.Name, Value =n.Value });

--EDIT--

var result = XDocument.Load(....)
            .Descendants("Sequences")
            .Select(n=> n.Descendants("NextItem")
                 .Union(n.Descendants("PreviousItem"))
                 .Select(n2 => new { ID = n2.Attribute("id").Value, Name = n2.Name, Value = n2.Value })
            );
