Answer 1

XNamespace ns = "xx";

var doc = XDocument.Load(xmlFilePath);
int idnt =
    int.Parse(
        doc.Descendants(ns + "PersonOtherIdentification")
        .Where(e => e.Element(ns + "IdentificationCategoryText").Value == "IDNT")
        .Single().Element(ns + "IdentificationID").Value);

Console.WriteLine(idnt);
