Using Linq to XML to create existing object based on class/model - working, but is there a better way?

A webservice I use (I have no control over it) returns an XML string, which I convert to an XDcoument and then create a list of objects of a particular type:

    private static List<ProductDetail> productList(XmlDocument _xDoc) {
        XDocument xdoc = XDocument.Load(new XmlNodeReader(_xDoc));
        var pList = from p in xdoc.Root.Elements("DataRow")
                  select new ProductDetail
                  {
                      Product  = (string)p.Element("Product"),
                      ProductDesc = (string)p.Element("ProductDesc"),
                      ExtraKey = (string)p.Element("ExtraKey"),
                      SalesGroup = (string)p.Element("SalesGroup"),
                      Donation = (string)p.Element("Donation"),
                      Subscription = (string)p.Element("Subscription"),
                      StockItem = (string)p.Element("StockItem"),
                      MinimumQuantity = (string)p.Element("MinimumQuantity"),
                      MaximumQuantity = (string)p.Element("MaximumQuantity"),
                      ProductVATCategory = (string)p.Element("ProductVATCategory"),
                      DespatchMethod = (string)p.Element("DespatchMethod"),
                      SalesDescription = (string)p.Element("SalesDescription"),
                      HistoryOnly = (string)p.Element("HistoryOnly"),
                      Warehouse = (string)p.Element("Warehouse"),
                      LastStockCount = (string)p.Element("LastStockCount"),
                      UsesProductNumbers = (string)p.Element("UsesProductNumbers"),
                      SalesQuantity = (string)p.Element("SalesQuantity"),
                      AmendedBy = (string)p.Element("AmendedBy")
                  };
        return pList.ToList();
    }

This works fine and is very fast. However it means I have to maintain this code separately from the model if it changes and I was just wondering if there was a shortcut to avoid me having to specify each individual field as I'm doing? I already have a class for ProductDetail so is there some way of using that at the object level? I've a feeling that the answer may be "yes, but using reflection" which will probably have a negative impact on the process speed so is not something I'd be keen on.
