hello,
I've 2 questions :

1 - I'm looking for a method to update an XML Tree with PL/SQL (and/
or) XSLT... but this update must be differential...
2 - If I use triggers at update time how can I get the old node
fragment (like :OLD operator in standard SQL ??) after update...

any idea to do this ??

Thanks for your help...
regards.
