Visio 2010 forward engineering to Oracle 10g xe

Question

I've been googleing but maybe I'm not using the right words, so:
I have a ER diagram made in Visio 2010, and I what to do a forward engineering to an Oracle database.

I've found a forward engineering plugin for Visio 2010 but this generates a MS SQL Server script, and the diagram has lots of tables, so editing the script is a last resort.

Can you please recommend me a tool/plugin, that can somehow make the Visio 2010 diagram in script for Oracle or a MS Sql Server to Oracle converter or some tool that can generate Oracle script from the Visio 2010 supported export formats (.vsd, .vdw, .vdx, .dwg, .dxf ...) ?

Thanks
