Hi Larry,

I'm trying to figure out what your wanting to do with the data once its in
mysql?  At first it seemed you didn't want to put it in as a lob because
you might want to query on the data in different ways (kind of an
assumption on my part, but a common reason to do this).  Then, you thought
about making a very generic schema (parent-node) which really doesn't lend
itself well to this goal.

Could you explain what you plan to do with the data in mysql and maybe a
little about the goal of the application?  Is this app specific to this
data, or are you looking to build an app that can take any schema defined
XML file, ingest it, and allow you to do some work with it?

Why is a lob not appropriate for your needs?
