Hi! If anyone should be in need of a parser for the language EXPRESS, here is one:
http://savannah.nongnu.org/cgi-bin/viewcvs/okstraperl/okstraperl/express2perl/okstra-parse.pl It is far from perfekt, but for my purpuse of analysing the OKSTRA-Data-Format ( www.okstra.de ) it works. OKSTRA is a object modell describing road infrastructure. EXPRESS is a language to describe objects, as far as i know mainly used to intercange CAD data. If youre interested in my work on this, have a look at http://savannah.nongnu.org/projects/okstraperl/ Ingo
