Not sure actually. I always do:
my_xml = new XML();
my_xml.ignoreWhite = true;
To ensure whitespace doesn't fubar my parsing. So, I'd assume yes since
whitespace is 1 extra thing to parse.

Perfect, thanks for all your help. Ill see what I can do to cut the
size out. If there is whitespace in the xml being sent back, could that
affect the parse time?
