Abstract: A system and method is disclosed for adding dynamic information to XML source data without substantial, or preferably any, modification of the underlying source code and without requiring the writing of any XSLT extension functions. The addition of dynamic information enables a user to customize XML source data for display based on parameters known only at run-time. The present invention receives various run-time and system parameters, uses the parameters to construct queries, and executes the queries against internal and/or external data sources. Datasets that are generated based on query execution are converted to XML document fragments and an XSL Transform converts the XML document fragments into a desired markup language file for presentation within a browser application.
