Dinesh and Kent - I've been lurking along as you run this problem to ground. The syntax you are working on looks very slippery, and reminds me of some of the issues I had writing a generic street address parser with pyparsing (http://pyparsing.wikispaces.com/file/view/streetAddressParser.py). Mailing list companies spend beaucoup $$$ trying to parse addresses in order to filter duplicates, to group by zip code, street, neighborhood, etc., and this citation format looks similarly scary.
Congratulations on getting to a 95% solution using PLY. -- Paul _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
