Ibve done a lot of this over the past 4 years, as youbll be aware from
Balisage and XMLPrague, first using Gunther Radermacherbs parser generator,
so tomorrow morning (26th) Ibll reply at length. You certainly can get a
full parse tree in XML that can be XSLTbd to another form and the reverse to
text is pretty easy....
