XMLSP 0.5 was released today.
If you are not interested in DOM support, you won't find anything new in core xmlsp comparing to previouse versions.
The next release will probably fix some bugs in DOM, add support to convering DOM back to XML and probably some cleanup.
A usual, please report any bugs you may have found in xmlsp code.
This is a critical upgrade, since it fixes bugs in core XML parsing routine which produced invalid output.
If you are using older versions I think you should upgade XMLSP now.
If you ever find a bug, please report it here on sourceforge or send me an e-mail.
Thanks.
XMLSP is a simple XML stream based parser released under BSD license. If you need a one file XML parser in less than 20kb of code - try it now.
