I don't know precisely how you can do it - but ruby has a built in XML parser for databases.
Though changing schema over time is a bit annoying (and bad practices as well in my opinion) You can't set up your database to deal with a changing schema.

I have an requirement of parsing an xml to db.
XML file has a schema and it is subjected to change over a period of time. I want to know how to map this xml to Database table.
Is this something like XSD to Dynamic class to ActiveRecord. I am new to this. How can I do this please suggest the me the methodology to follow or the gems can I use.If the attributes will change over time then you'll either have to write migrations for this as it happens or use some form of serialization for the variable data ( hstore or json in postgres, rails serialization etc.). Also worth considering whether a relational model is the best fit for your data.Fred
