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 })
            );

Answer 2

I'm not sure I understood the question, but you can easily take element/attribute value inside LINQ to XML select statement:

var EnumerableContent = from item in XElement.Load("file.xml").Elements("NextItem")
              select new Extract() { name = item.Value, _id = (int)item.Attribute("id") }

Answer 3

hi i think this is what you expect.

List<XElement> lstXElements = new List<XElement>();
        lstXElements.AddRange(GetDescendants("NextItem"));
        lstXElements.AddRange(GetDescendants("PreviousItem"));

        List<Extract> lstExtract = new List<Extract>();

        foreach (XElement objElement in lstXElements)
        {
            Extract objExtract = new Extract();
            objExtract._id = Convert.ToInt32(objElement.Attribute("id").Value);
            objExtract.name = (objElement.Name).LocalName;
            lstExtract.Add(objExtract);
        }
List<XElement> GetDescendants(string strDescentName)
    {
        return ((XDocument.Load(Server.MapPath("XMLFile1.xml"))
            .Descendants(strDescentName))
            ).ToList<XElement>();
    }
