Loading xml into relational tables.

Question

I was wondering if anyone knows of a product/libraries which does the following:
-Read data from a relational Database (multiple tables) and generate XML files based upon an XML Schema or DTD file?
-Read XML files and load data into a relational Database.
-Graphical Interface for performing the maps (perhaps based upon .xslt). ie.... Mapping of the XML Schema to Multiple Database Tables, Performing Joins etc...
-Ability to connect to any type of Relational database (not just Oracle). Which rules out XML DB.

Answer 1

This product does look to be ok, however it is missing a couple features that I would like the product to have.
I would like this product to be able to insert/update data across multiple tables. Being able to do such things as generate foreign key relationships.
It doesn't seem as though the XML being generated can be customized very easily. Some XML formats I deal with are very complex (such as X12/EDI).
I would really like a graphical mapper.
Here is a note from the doc:
Storing XML Data Across Tables
Currently the XML SQL Utility (XSU) can only store data in a single table. It maps a canonical representation of an XML document into any table or view. But there is a way to store XML with XSU across tables. You can do this using XSLT to transform any document into multiple documents and insert them separately. Another way is to define views over multiple tables (using object views if needed) and then do the insertions into the view. If the view is inherently non-updatable (because of complex joins), then you can use INSTEAD OF triggers over the views to do the inserts.
This product looks really good, I was hoping that Oracle had something comparable:
