Oof, I see that you have multiple "Layer" entries, with different qualifying labels. Since the dicts use "Layer" as the key, you only get the last "Layer" value, with qualifier "PRBOUNDARY", and lose the "Layer" for "METAL2". To fix this, you'll have to move the optional alias term to the key, and merge "Layer" and "PRBOUNDARY" into a single key, perhaps "Layer/PRBOUNDARY" or "Layer(PRBOUNDARY)" - a parse action should take care of this for you. Unfortnately, these forms will not allow you to use object attribute form (md.Layer.lineStyle), you will have to use dict access form (md["Layer(PRBOUNDARY)"].lineStyle), since these keys have characters that are not valid attribute name characters.
Or you could add one more level of Dict nesting to your grammar, to permit access like "md.Layer.PRBOUNDARY.lineStyle". -- Paul -- http://mail.python.org/mailman/listinfo/python-list
