> One of the harder things with XMPP is that it is a badly-formed document up until the connection is closed. You need a SAX-style/event-based parser to handle it.

That is a common misconception, although I am not sure of its origin. I know plenty of XMPP implementations that use an XML pull parser.

It's possible by blocking the thread that's reading the XML, but now you're in thread-per-client territory, and that doesn't scale.

Smack uses an XML pull parser and non-blocking I/O. It does so by splitting the XMPP stream top-level elements first and only feeding complete elements to the pull parser.

I don't see any opportunity not to block when calling "next"
