Guidance Needed: Loading Hierarchical XML Into Relational Tables

I've got a lot of XML like this (simplified):




Code Snippet





... 8 MORE


... 9 MORE TIMES






I need to get this into three existing SQL Server 2005 tables, each with identity columns for their primary keys:




Code Snippet
CREATE TABLE ELEMENT1 (

[ID] INT IDENTITY
)

CREATE TABLE ELEMENT2 (

[ID] INT IDENTITY,
[ELEMENT1_ID] INT
)

CREATE TABLE ELEMENT3 (

[ID] INT IDENTITY,
[ELEMENT2_ID] INT
)





With primary and foreign keys as you'd expect, and, of course, many more columns!

How would I get this into tables through SSIS, preferably in a high-performance manner (there may be several gigabytes of XML to load).

The issue, of course, is that in order to insert an ELEMENT2 row, I need the ID from the coresponding ELEMENT1, etc.

Any ideas or pointers to articles would be welcome.
