Re: [xml-dev] To continue parsing after a fatal error.

[Anoop A V <anoop_scorpio@hotmail.com>]

Hi Dave,
    I guess the diagnostic is correct. And I think I should either
preprocess the XML as you have said, or split the file into smaller files as
Tim Bray has suggested. I hope the 'Out of memory' situation won't arise. It
was precisely for this reason that I decided to use SAX rather than DOM. In
fact, using DOM for an 800 MB file is unthinkable.

Thanks for your suggestion.
Anoop.
