Re: XML differencing anyone?

So are you trying to do the XML differencing on an Apache server like I am?

Well, I've been running in circles looking at this stuff so I started a 
list of all the XML differencing apps that I've come across.  I tried to 
list each app with a URL, a license type, and positives/negatives about 
it.  '?' means I'm not quite sure.  If anyone has any additions or 
corrections, I'd be glad to hear it!
