Re: XML DOM issues in IE and Opera

Grant,

Thanks for the words about nodeFromID in IE.  I just can't understand
why anyone bothers to contiue writing and publishing standards if the
industry is going to conitue to ignoring them.  I've got more forks in
my code than my silverware cabinet.  :(

I still can't get Opera to work...not that I am terribly concerned
about it.  It just eats me up to not have a single block of code work
in all JS environments..

Thanks,
Jim
