NYCPHP Meetup

[pswebcode, nyc]

Looks sleek...  ...but regarding any documentation (full list of functions,
say) for the updated DOM, XSLT and XPATH functionality? 

And if I remember right... SAX, XSLT and DOM XML libs will all be installed
by default on both *nix and Windows?

I have been using DOMXML functions at this time and several web hosts would
not install the library, namely because it is marked as Experimental.

Yes, and kinda.  The SAX extension (ext/xml) will remain the same.

Code that uses the DOM extension will need to be rewritten.  The DOM
extension has always been experimental, and never really worked.  Now it
will, and it will be 100% DOM 2 (and mostly DOM 3) compliant.  The API for
the XSLT extension is also completely changed.

Yep, that's it.  SimpleXML is actually quite powerful.  For example, I wrote
a full WSDL parser using simplexml.  It supports Xpath, Schema and the full
XML infoset.
