Re: Parsing Using SAX

Ok,

Im going to include my code for this problem.
I get an error when the parse function is called:
parser->parse(XMLfile)....Ive got no idea why

Also this was formed from the SaxCount Code included with the Xerces distro.

Currently I dont see it doing anything. I need to be able to change variable
& containers in the DocumentHandler Class

Cheers
Alex
