Add perent element

I want to add perent element to existing element in xml variable (SQL 2005).
I solve that problem with:
DECLARE @.a xml
SET @.a =
N'<EVENT_INSTANCE><a>CREATE_TYPE</a><b1>2005-10-14T01:58:28.070</b1><c>51</c></EVENT_INSTANCE>'
SELECT @.a
SET @.a.modify('
insert (<AddElement></AddElement>)
after (/EVENT_INSTANCE/a)[1]')
select @.a
SET @.a.modify('
insert /EVENT_INSTANCE/b1
as first
into (/EVENT_INSTANCE/AddElement)[1]')
select @.a
SET @.a.modify('
delete /EVENT_INSTANCE/b1')
SELECT @.a
Is there any simplier solution.
Thanks
Dear Ana
There are two ways at the moment to insert a new intermediate layer. The one
you show below, the other (which may be worse), is to decompose the tree and
use the FOR XML PATH mode to recompose the tree with the new level in
between.
The three updates below - unlike the FOR XML approach - will only update the
subtrees involved in the updates and not the whole XML document.
We are looking into extending the update language to make this a bit better,
but in general, inserting new levels into an XML tree will always be a
somewhat costly operation since your three steps would have to be executed
in any case (due to the node-id implementation that encodes the position in
the tree).
Best regards
Michael

select @.a.query('
for $a in /* return (
element EVENT_INSTANCE {$a/a, element AddElement {$a/b1}, $a/c}
