Abstract: A system and method is provided for implementing a dynamic form using file data retrieved from an external file source. An application executing on a server computer is responsive to a form request received from a user system computer to transform the retrieved file data into a format that includes new input elements. Unique namespaces are assigned to each of the new input elements, and the requested form and transformed file data are transmitted to the user system. The application is configured to create new XML file data that is mapped to the original XML file data in response to a user of the user system inputting data into the form. The new XML file data is compared to the original XML file data to identify missing elements. Missing elements are inserted into the new XML file data, and the new XML file data is stored in a memory.
