SQL Server 2012 :: Nested FOR XML Path

I'm trying to reverse engineer an XML output based on a client's need of a very specific format. Besides the issue of getting the XML declaration written in and removing NULLs, I'm having an issue with a three times nested PATH query.

So far the document almost has the correct format, except for the first nested root being returned. Is there any way to prevent this?

*some data redacted

Query:

DECLARE @a XML
SET @a =
(SELECT FileCreationDate,
(
SELECT PCE_TPD.PJN,
(
SELECT top (2) TaskCode, TaskName, RSI, TAFFD, AFD, Notes, PID, CUSID, NeedToBeNA

[Code] ....

Current Output (first few lines):

<TDBUIData xmlns="http://www.xxxxx">
<TDBUIData12 xmlns=""> --NEED TO ELIMINATE THIS
<FileCreationDate>2014-10-15T23:23:00</FileCreationDate>
<TDBUIDL>
<PJN>MRWSH010824</PJN>

[Code] ...

Desired Output (first few lines):

<TDBUIData xmlns="http://www.xxxxx">
<FileCreationDate>2014-10-15T23:23:00</FileCreationDate>
<TDBUIDL>
<PJN>MRWSH010824</PJN>
<TaskData>
