A document management system that converts documents from different sources such as scanners, Fax machines, and workstations into electronic documents and provides file management to manage the document storage and retrieval. The system comprises parsing engines that subdivide the document presentation into multiple presentation zones, parse data of each presentation zone with different parsing program or programs to provide output data in format or formats preferable for said zone, and reconstruct the document by recomposing the output presentation of all presentation zones.
