VCalSax is a simple Python module for managing scheduler data in XML. It enables loading data from VCalendar files into DOM trees, and to rewrite such trees as VCalendar files. To make such conversions, VCalSax defines a Sax parser which changes the VCalendar format to a specific XML format, and a XSL Transform to build VCalendar files. VCalendar is a standard format for scheduler data used in many calendar software (KOrganizer, Evolution, etc.).
