How to emulate SQLServer's ( INSERT INTO SELECT FROM .... OPENXML ) functionality in Oracle 9i ???

I am working on a project to port our SQLServer backend to Oracle. I am hoping to find a way to emulate
this SQLServer T-SQL functionality in PL/SQL where a single INSERT statement can be used to process multiple row inserts from an incoming XML document. The insert must also be able to handle a variable in the insert such as the @iNumber variable below that is not part of the XML document.

I've included a sample of the SQLServer code below and the results. 2 rows are inserted since there are two <Item> nodes in this document. I've tried several Oracle methods using XMLTYPE and DBMS_XMLDOM, but I have been unsuccessful so far. Any help would be appreciated.

• CREATE TABLE T ( C1 INT, C2 VARCHAR(10), C3 VARCHAR(10) )

delete from t

declare

@iDoc     int,
@vcXMLDoc   varchar(4000),
@iNumber   int

set @iNumber = 1
set @vcXMLDoc =
'<Log><Item><OldValue>jones</OldValue><NewValue>JONES</NewValue></Item><Item
><OldValue>smith</OldValue><NewValue>SMITH</NewValue></Item></Log>'

EXEC sp_xml_preparedocument @idoc OUTPUT, @vcXMLDoc

INSERT INTO T
  SELECT
   @iNumber,
   OldValue,
   NewValue

  FROM OPENXML(@iDoc, '/Log/Item/NewValue')

      WITH  (OldValue   varchar(255) '../OldValue',
        NewValue    varchar(255) '.' )

EXEC sp_xml_removedocument @iDoc

select * from t

C1 C2 C3
----------- ---------- ----------

1           jones      JONES
1           smith      SMITH
