I don't think the perfect library exists, because HTML has changed considerably since most Racket libraries were written.
I think xexpr do 90% of the job, but fails on the issues mentioned in that issue. I think the best option right now is either txexpr --- http://docs.racket-lang.org/txexpr/index.html or html-writing --- http://docs.racket-lang.org/html-writing/index.html But I think the perfect system is yet to be done. (I think it would have elements of these two, plus css-expr, for instance.)
