A METHOD AND COMPUTER-READABLE MEDIUM ARE PROVIDED FOR SELECTIVELY IMPORTING AND EXPORTING DATA IN ELECTRONIC DOCUMENT. AN IMPORT APPLICATION PROGRAM INTERFACE (API) MAY BE IMPLEMENTED TO IMPORT CONTENT FROM A HIERARCHICALLY STRUCTURED DOCUMENT, SUCH AN XML FILE. THE IMPORT API WORKS IN CONJUNCTION WITH A PARSER TO SCAN THE DOCUMENT AND EXTRACT CONTENT FROM SELECTED ELEMENTS, NODES, ATTRIBUTES, AND TEXT. THE IMPORT API ALSO UTILIZES A CALLBACK COMPONENT FOR PROCESSING THE EXTRACTED CONTENT. AN EXPORT API MAY ALSO BE IMPLEMENTED TO EXPORT DATA TO CREATE A HIERARCHICALLY STRUCTURED DOCUMENT, SUCH AS AN XML FILE. THE EXPORT API WORKS IN CONJUNCTION WITH A WRITER TO RECEIVE DATA AND EXPORT THE DATA AS ELEMENTS, NODES, ATTRIBUTES, AND TEXT IN THE HIERARCHICALLY STRUCTURED DOCUMENT.(FIG 4)
