NB: This example is *precisely* why I will never adopt MathML as an authoring format. Bowing and scraping at the alter of W3C is not worth using such a terrible syntax, not ever.
(Indented, that's

Which is still unforgivably horrible. I *think* it's trying to say $x^2 + 4x + 4$, but I'm not confident even of that.
Yeah, MathML looks like a machine-only format to me, begging the question why they don't use a more compact format.
I'm also unconvinced it's actually easier to parse than $x^2 + 4x + 4$.)
While parsing is a solved problem in theory, a lot of people use some regular expression kludges or similar atrocities in practice. Writing a proper parser is too complicated if your language doesn't have parser combinators. :) Regards, apfelmus -- http://apfelmus.nfshost.com
