Check if XML Element exists

Question

How can someone validate that a specific element exists in an XML file? Say I have an ever changing XML file and I need to verify every element exists before reading/parsing

Answer 1

 string name = "some node name";
    var xDoc = XDocument.Load("yourFile");
    var docRoot = xDoc.Element("your docs root name");

     var aNode = docRoot.Elements().Where(x => x.Name == name).FirstOrDefault();
                if (aNode == null)
                {
                    return $"file has no {name}";
                }
