Writing XML document to database via Stored Procedure

[boondocksaint20]

I've read some articles about XDB and XMLTYPE for Oracle 9i, and found one where you can parse static xml code in the Stored Procedure to write into a database table, but what I really want to find is a simple example of parsing an existing XML document inside an Oracle 9i Stored Procedure, then iterating through it and writing to a table. If anyone can show me how to do this I'd be very grateful.

Thanks!
