I think that this might be handled typically (like in WWW browsers) by
letting the subcomponents be handled by DLL's (dynamically linked library).
So one writes libraries of pure parsers, and hands over the text
subportions to them.

Perhaps you can get more info in a newsgroup, such as comp.compilers (which
is moderated by John R. Levine).
