I need help with complex LINQ to XML query in C#

I don’t know if the query I am trying to do is even possible but if one of you LINQ to SQL/XML guru’s can figure this out I will be so thankful and salute you as a LINQ God. My end goal is to identify all of the XML Models that are duplicates and show the CECID for all the duplicates except one. So lets say I have an Xdocument that looks like this:

Then in SQL Server I have a table called tApplianceTypeColumns that looks like this for a given appliance type:

ApplianceTypeIDApplianceColumnUniqueApplianceColumnName
100ReferenceNumber
101Brand
101ModelNumber
100EquipmentType
100CoolingType
100IceType
100IceMakerProcessType
100HarvestRateLbs24Hr
100EnergyCons_kWhPer100Lbs
100WaterCons_galPer100lbs
101RegulatoryStatus

So here is what I started with but I am far from being close:



So really I want to be able to group by Brand, Model Number, and RegulatoryStatus which are the columns in the tApplianceTypeColumns table that have the ApplianceColumnUnique bit column set to true. The number of true bits could vary depending on the ApplianceTypeID I am looking up in that table. Additionally, I also need to include two elements in the grouping that are never in the tApplianceTypeColumns table and those elements are Action then ManufacturerCode followed by all the other unique elements from the tApplianceTypeColumns in no specific order. So ApplianceTypeID is a known parameter that will be passed to the query. So for any set of duplicates I need to display the CECID for the 2nd and subsequent duplicates so that I can take those CECID’s and do lookups in other tables to change their status. But this first step is tough. I don’t care which of the duplicates does not get displayed. I just need to display all others except 1. I hope I have explained this well enough.

UPDATE: I was able to get a solution for this on StackOverflow.com. Here is a link to the solution.
