IIRC most of them - at least that source code was freely available. 
The actual licence details may have been different. I can count Tim 
Bray's Lark, Norbert Mikola's tool (I forget its name, but it was 
seminal in developing XML) and expat and a Java equivalent from James 
Clark. Murato Makoto's tools. There was a good deal of stuff from IBM 
alphaworks - not sure how much of that was technically OS but it has 
inspired the development of apache.xml. I made a consistent appeal 
for OS on XML-DEV and I remember when (I think Fujitsu) made 
something available with a phrase like "We've listened!... and now we 
have released this under OS".

I can't think of many original XML parsers which were closed - 
certainly none which were costs-money. But memory may play tricks.
