Why not write your own damn parser and handle the whole problem on a
character-by-character basis if you want. All you have to do is debug it and
make it work right.

or you could just do what software engineers have been advocating for
decades and make use of an existing *reusable library* that is already out
there. That way you help yourself, by taking advantage of debugging that has
already been done.
