In playful spirit I disagree. Translators can be the hardest thing
to write. After writing my own XML parser, I can see that the goal
of XML being easy to write parsers for has been adequately achieved.
The hard part is transforming the thing into anything that is going
to a printed document. For instance a transform to PostScript is less
than trivial. You have to keep track of placing words on the page,
when a new page begins, where things were (i.e. what page) that are
referenced in another part of the document, and I have not even
mentally considered things like images (converting them to eps [although
I suppose that could be done by some helper program you did not write]).
Actually, long as I am blabbing, having functional XML parser, what is the
easiest language to translate the XML AST to in order to produce a
_nice_ printed document?
