Hello Everyone,
        Well, the subject says it all really. I have
a few jobs that I -could- write perl to transform the
xml into inserts, however, I would prefer to use XSLT
and learn as I go. Another feather in my cap and all
that.
Stef,

I have done this with an Oracle database. The latter actually has a mechanism for directly updating the database from XML but we found it to be very slow. The process you show will work but if you are inserting a lot of rows then the round trips to the database will be a significant component of the run time. Oracle (and some others) provide mechanisms for inserting a lot of rows in one bulk operation, although they may not be available from an interactive SQL processor - you may need to create a program to do it. The most efficient way to do this is probably to write your data out to a delimited text file and use the database load utility. This can result in order-of-magnitude-level improvements in load speed over separate INSERT statements This approach would require that your data rows have the same data elements and be loaded to the same table; I assumed from your example that this might be the case
