Cannot access certain field in the XML file using XML to LINQ

I'm receiving a xml feed containing car adverts from another site.
And when I try to read this using XML to LINQ I get 'Object reference not set to an instance of an object.
on certain elements.
I can get 8 out of 10 elements, but then I get  'Object reference not set to an instance of an object.' on the rest.
The elements I'm having problems with are commented out in the code attached.

URL to complete result from feed: http://dev2.spire.as/feed.aspx
string feedURL = @"http://www.url-to-feed.com";
        XDocument rssFeed = XDocument.Load(feedURL);
        var posts = from a in rssFeed.Descendants("element")
                    select new Article
                        //Image = a.Element("MMO").Value,
                        Price = int.Parse(a.Element("PRICE.AMOUNT").Value),
                        ModelSpecification = a.Element("CAR_MODEL.MODEL_SPECIFICATION").Value,
                        //Disposed = int.Parse(a.Element("DISPOSED").Value),
                        Make = a.Element("CAR_MODEL.MAKE").Value,
                        Mileage = int.Parse(a.Element("MILEAGE").Value),
                        Heading = a.Element("HEADING").Value,
                        ArticleID = int.Parse(a.Element("ADID").Value),
                        Year = int.Parse(a.Element("YEAR_MODEL").Value),
                        Location = a.Element("LOCATION").Value,

The top solution didn't work for me, but I found this one online that did.
var result = from s in data.Descendants("student")
             let user = s.Attribute("user")
            where user != null
             select new LINQandXML.Student
                 Family = s.Element("family").Value,
                 Given = s.Element("given").Value,
                 User = s.Element("user").Value
