Actually, this isn't a bad thing. Writing your own XML validator is an
excellent way to gain proper comprehension of XML. Look up all the
specifications and be sure that your parser complies with them, and
you'll truly understand what XML is all about.

For production code, it's often better to take a ready-made solution,
if only to save you the trouble of coding it. But for learning, taking
someone else's code can lead to black-box mentality - "I push this in
here and I get that out there" - which can lead to all sorts of
ridiculous piles of overlaid protocols. Yes, I've seen some pretty
dumb stuff floating around!
