Import XML using SQL Server, the problem is it is returning only one record at a time and I want all records in one go

Question

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX)

SELECT @XML = 
N'<ROOT>
   <B2A>
    <B2A.01>
     <B2A.01.1>00</B2A.01.1>
    </B2A.01>
    <B2A.02>
     <B2A.02.1>LT</B2A.02.1>
    </B2A.02>
   </B2A>
   <L11>
    <L11.01>
     <L11.01.1>1123</L11.01.1>
    </L11.01>
   </L11>
   <L11>
    <L11.01>
     <L11.01.1>120001502140</L11.01.1>
    </L11.01>
    <L11.02>
     <L11.02.1>BN</L11.02.1>
    </L11.02>
   </L11>
   <L11>
    <L11.01>
     <L11.01.1>KDC</L11.01.1>
    </L11.01>
    <L11.02>
     <L11.02.1>11</L11.02.1>
    </L11.02>
    <L11.03>
     <L11.03.1>11</L11.03.1>
    </L11.03>
   </L11>
 </ROOT>'

EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML

My approach

SELECT 
T1.be.value ('(B2A/B2A.01/B2A.01.1)[1]' ,'nvarchar(4)')  as [tcode],
T1.be.value ('(B2A/B2A.02/B2A.02.1)[1]' ,'nvarchar(4)')  as [apptype],
T.te.value ('(L11/L11.01/L11.01.1)[1]' ,'nvarchar(60)')  as [id],
T.te.value ('(L11/L11.02/L11.02.1)[1]' ,'nvarchar(6)')   as [Ref id],
T.te.value ('(L11/L11.03/L11.03.1)[1]' ,'nvarchar(160)') as [DESCRIPTION]
FROM    (
    SELECT  @xml AS x
    ) xml  
x.nodes('/ROOT/L11') T(te)
outer apply x.nodes('/ROOT/B2A') T1(be)

But here the problem is it is giving only one record at a time and I want all records in one go.

This is what I am getting

tcode	apptype	id	Ref id	DESCRIPTION
00	LT	null	null	null

and if there are multiple records then it should show like this

tcode	apptype	id	Ref id	DESCRIPTION
00	LT	1123	null	null
00	LT	120001502140	BN	null
00	LT	KDC	11	11

Try this:

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX)

SELECT @XML = N'<ROOT><L11><L11.01><L11.01.1>1123</L11.01.1></L11.01></L11><L11><L11.01><L11.01.1>120001502140</L11.01.1></L11.01><L11.02><L11.02.1>BN</L11.02.1></L11.02></L11><L11><L11.01><L11.01.1>KDC</L11.01.1></L11.01><L11.02><L11.02.1>11</L11.02.1></L11.02><L11.03><L11.03.1>11</L11.03.1></L11.03></L11></ROOT>';


SELECT ROW_NUMBER() OVER (ORDER BY T.c)
      ,T.c.query('.')  
      ,T.c.value ('(./L11.01/L11.01.1)[1]' ,'nvarchar(60)')  as [id]
      ,T.c.value ('(./L11.02/L11.02.1)[1]' ,'nvarchar(6)')   as [Ref id]
      ,T.c.value ('(./L11.03/L11.03.1)[1]' ,'nvarchar(160)') as [DESCRIPTION]
FROM @XML.nodes('ROOT/L11') T(c);

And for your edit, you can get the data like the following:

 SELECT T.c.value ('(./B2A.01/B2A.01.1)[1]' ,'nvarchar(60)')  as [tcode]
       ,T.c.value ('(./B2A.02/B2A.02.1)[1]' ,'nvarchar(6)')   as [apptype]
       ,T.c.value ('(./L11.01/L11.01.1)[1]' ,'nvarchar(60)')  as [id]
       ,T.c.value ('(./L11.02/L11.02.1)[1]' ,'nvarchar(6)')   as [Ref id]
       ,T.c.value ('(./L11.03/L11.03.1)[1]' ,'nvarchar(160)') as [DESCRIPTION]
FROM @XML.nodes('ROOT/*') T(c)

and then to use T-SQL to shape it the way you want. For example:

 WITH DataSource AS
 (
     SELECT T.c.value ('(./B2A.01/B2A.01.1)[1]' ,'nvarchar(60)')  as [tcode]
           ,T.c.value ('(./B2A.02/B2A.02.1)[1]' ,'nvarchar(6)')   as [apptype]
           ,T.c.value ('(./L11.01/L11.01.1)[1]' ,'nvarchar(60)')  as [id]
           ,T.c.value ('(./L11.02/L11.02.1)[1]' ,'nvarchar(6)')   as [Ref id]
           ,T.c.value ('(./L11.03/L11.03.1)[1]' ,'nvarchar(160)') as [DESCRIPTION]
    FROM @XML.nodes('ROOT/*') T(c)
)
SELECT MAX([tcode]) OVER()
      ,MAX([apptype]) OVER()
      ,[id]
      ,[Ref id]
      ,[DESCRIPTION]
FROM DataSource
