that is certainly possible, but you need to modify the parser.

you are probably not using the latest version. Earlier versions of
Pier generated that kind of code and it is invalid to have a div
(block-element) inside of a <p>. The current version of Pier
generates <div class="paragraph">. This is valid and can be easily
configured using CSS selectors, so that i behaves different to
paragraphs in a Wiki page.

I do only black-box testing of the parser: I give input strings and
check what is coming back. The tests of the Pier parser actually
cover all the rules of the code (at least they did the last time I
checked). I guess nobody wants to directly mess with the transition
tables, that is too low-level. Mhh, it would be cool to have a tool
generating the finit set of valid programs of the maximal size n that
can be parsed by a given SmaCC parser, this means to use the parser
the inverse way.
