Hi Andreas, Thanks for that starting point. But I have no success with any of 3 files (it is need to be modified ClassicStructuredText.py, DocumentClass.py, HTMLClass.py) Does somebody have some modified version of STX sources or some how-to? Many thanks, J. Lukesh ---------- Odesílatel: Andreas Jung <lists@andreas-jung.com> Checkout lib/python/StructuredText/DocumentClass.py. But I recommend to keep your fingers from the code unless you really know what you are doing.
