An example is <URL: http://en.wikipedia.org/wiki/XMPP#XMPP_via_HTTP_and_WebSocket_transports>. The "document" is potentially infinitely long. The elements are messages. The programmer would rather process the elements as DOM trees than follow the meandering SAX parser. Marko -- https://mail.python.org/mailman/listinfo/python-list
