I've finally got a parsed tree with all syntax switches needed. Maybe it's not a perfect algorithm but at least it works. The only problem with that tree is that there is a new paragraph at every syntax switch. When I'll fix that I will work on visitin+accessing stuff to get it working correctly.
Actually there are more frequent (when something is done) reports on my site. See a News section for them http://kamikaze.seasidehosting.st/
