There's some old example code to do this for ArgoUML XMI files available at
http://objectsbydesign.com/projects/xmi_to_html.html  I think it was written
back in the UML 1.3/XMI 1.0 days, so it would need to be updated to UML
1.4/XMI 1.2, but it might provide a useful starting point for you.

AndroMDA generates Hibernate mapping files from ArgoUML XMI files.
http://andromda.org/  There are probably other generator frameworks or MDA
packages that do the same.
