对于以下代码,LINQ to XML的等价物是什么？

    public List GetList()
    {
        if (File.Exists(this.xmlFilePath))
        {
            XDocument doc = XDocument.Load(this.xmlFilePath);

            var listings = from row in doc.Root.Elements("listing")
                           select new Listing
                           {
                               A = (string)row.Element("A"),
                               B = (string)row.Element("B"),
                               C = (string)row.Element("C"),
                               D = (string)row.Element("D"),
                               E = (string)row.Element("E")
                           };

            return listings.ToList();
        }
        else
        {
            return new List();
        }
    }
