If you can, I'd recommend not storing the data in XML; instead:
- map out its meaning to tables
- parse the XML when importing
- store in a normalized table
- and edit normally.
- When needed, you'll generate using the standard XML buildings in rails.
If you do that, you'll have a much better experience in rails.
If you can't, because you don't know the schema, then look at nokogiri
