If I'm correctly understanding your very broad and general requirement...

This could be accomplished with an XFA form with an flowed, repeatable subform that contains known-name fields for your data, and filling those fields with data from an XDP (which is an XML format). The only thing you would need to do yourself is design a way of converting any input format you want to support to XDP so that it can be merged with the XFA form.

Apologies if I missed the point.
