[Expat-discuss] not well-formed (invalid token) error

Wed Apr 8 01:17:06 CEST 2009

Krishna:

I'm afraid you're fighting a losing battle...  You're trying to use
the wrong too.  I have never looked into XHTML, put my gut instinct
tells me it would be an valid XML expression of HTML... and that is
where you need to go if you wish to continue to use eXpat as you're
currently attempting.  You could try and write some front end filter
to convert HTML that is not valid XML into valid XML, but that seems,
at first blush, to be a lot of work, and probably not worth the
payoff.  There must be some HTML parser out there that you could
use...  but I have never had the need and so cannot supply you with a
reference for one.

Good luck,
  Nick
