My expected results, note the very first line/node is request. Unlike the results I get above, i need the node and attribute to be on the same line:

      **<request service=quoteRequest">**

          <Header>
            <Action>Add</Action>

          </Header>
          <Shipment>
            <Status />
            <Enterprise customerAcctNum="CustAcctNum" name="Name">Enterprise Name</Enterprise>

I've tried many different things and still cant get it to work correctly. Anybody have any ideas? Thanks much!

Sorry but I want to take a step back and question why you are making the data as complex as it is with selects over and over and over? I would break it up into sections potentially of Shipment, Shipper, etc if it very complex and making a giant tablix but you should be able to make the elements independent of any tree structure and then readd them as needed. In a mock up I can show what I mean. Using the more explicit 'XML Path()' you have more options for creation of artifical nodes and don't have to nest selects just for creating node names. EG:

DECLARE @People TABLE (PersonId INT IDENTITY, PersonName VARCHAR(128));

INSERT INTO @People (PersonName) VALUES ('Brett'), ('John'), ('Mark'), ('Shawn'), ('Ryan'), ('Kevin');

DECLARE @XmlResults XML = 

(
SELECT 
  CAST(
    Replace(
    (SELECT 
      'quoteRequest' AS "@service"
    , 'Add' AS "QuoteRequest/Header/Action/*"
    , 'generation' AS "QuoteRequest/Header/Date/@type"
    , 'MM/DD/YYYY HH:MM' AS "QuoteRequest/Header/Date/*"
    , '' AS "QuoteRequest/Shipment/Status/*"
    , 'CustAcctNum' AS "QuoteRequest/Shipment/Enterprise/@customerAcctNum"
    , 'Name' AS "QuoteRequest/Shipment/Enterprise/@name"
    , PersonName AS "QuoteRequest/Shipment/Enterprise/*"
    , 'earliest' AS "QuoteRequest/Dates/Pickup/Date/@type"
    , FORMAT(GETDATE(), 'yyyy-MM-ddTHH:mm:ss.fff', 'en-US') AS "QuoteRequest/Dates/Pickup/Date/*"
    , 'latest' AS "QuoteRequest/Dates/Pickup/DateTwo/@type"
    , FORMAT(GETDATE(), 'yyyy-MM-ddTHH:mm:ss.fff', 'en-US') AS "QuoteRequest/Dates/Pickup/DateTwo/*"
    From @People
    FOR XML PATH('request'), ROOT('Requests'))
    , 'DateTwo', 'Date')
  AS XML)
)

--XML as is
SELECT @XmlResults

--XML parsed for one request at a time in my series.
SELECT x.query('.')
FROM @XmlResults.nodes('Requests/request') AS y(x)
