The present invention relates generally to computers and computer databases, and more specifically, to a method of and system for converting between Object-oriented classes and markup languages. One aspect of the invention is broadly defined as a method for converting data from a markup language format to an Object model, comprising the steps of: identifying an input markup language code, a destination Object and a markup schema; determining mappings between the markup schema and the destination Object, distinguishing between data elements and organizational elements of the input markup language code; traversing the input markup language code, following paths in accordance with whether the mappings are data or organizational; and instantiating corresponding software Objects.
