importing xml document to multiple related table with identity column.

Hi,
I am new to XML and looking for some information and suggestion. I need
to import xml document into related table having identity column, could
any one let me know which is the best way to do this. detail
information:
suppose i have 3 xml document call a.xml, b.xml and c.xml. I need to
bring information from these xml document to 3 different table whcih
are related with identity key (primary identity key).
table A: has identity key (A1)which is also a primary key with other
field.
table B: has identity key (B1)which is a primany key, column A1 which
is FK and other field
table C: has identity key (C1) which is a primary key, Column A1 wihic
is FK and other field.
xml document a.xml contain the information or record for table A, b.xml
contain for table B and c.xml contain for table C.
First i would like to bring the information from a.xml to the table A,
withour identity key from xml, it will be generated to the sql server
(this is only one row of data), the identity generated with be the max
of identity. I will like to bring this max of identity or identity
field just generated along with othere infromation from b.xml to table
B, similar to table C.
Could any one let me konw which is the best way to solve this problem.
Thanks in advance.
Indra.Can you post DDL (CREATE TABLE statements) for your tables, an example of
the XML document you're trying to import, and a list of which fields from
the XML correspond to which columns in the tables?

nText.
Load the XMLs into XMLDOcuments using sp_xml_preparedocument to read xml
contents.
you can check how to use this extended stored procedure here..

_267o.asp
First prepare the insert statement to Insert Into Table A. Get identity
column with Select Scope_Identity()
use this to insert into Table B and Table C by preparing the insert
statements using XML B and C.
you will have to loop through the records. The best way would be to Insert
all records into Table A. Then write statements insert into
TabeB and C. it can be done simply with just 3 insert statements. but you
need to map tTable A records with B and C.

If there are multiple rows inserted, SCOPE_IDENTITY() will not do the
job. And there is no reason to do a loop of any kind. The entire thing
should be able to be done in a set-based manner.|||Hit send too soon on the last message.
Something like this... no loops necessary:
use tempdb
go
create table abc(somedata char(10), abcID int identity(1,1) primary key)
go
create table def(somedata char(10), abcID int references abc(abcid))
go
declare @.xmldoc varchar(8000)
set @.xmldoc =
'<anode>
<another somedata="something">
<blah someother="else"/>
</another>
<another somedata="something2">
<blah someother="else2"/>
</another>
</anode>'
DECLARE @.hdoc int
EXEC sp_xml_preparedocument @.hdoc OUTPUT, @.xmldoc
insert abc (somedata)
SELECT somedata
FROM OPENXML (@.hdoc, '/anode/another')
with (somedata char(10) '@.somedata')
insert def (somedata, abcid)
SELECT x.someother, abc.abcid
FROM
(SELECT somedata, someother
FROM OPENXML (@.hdoc, '/anode/another')
with (
somedata char(10) '@.somedata',
someother char(10) 'blah/@.someother')) x (somedata, someother)
JOIN abc ON abc.somedata = x.somedata
EXEC sp_xml_removedocument @.hdoc
go
select *
from abc
go
select *
from def
go
drop table def
drop table abc
