In 5.1.5:

SELECT ExtractValue(’<a>foo<b>bar</b></a>’, ‘//b’);

	bar

SELECT UpdateXML(’<a>foo<b>bar</b></a>’, ‘//b’, ‘zig’);

	<a>foozig</a>

XSLT implementation on its way, maybe? :)

In 5.1.6:

CREATE EVENT e
ON SCHEDULE EVERY 1 DAY
ON COMPLETION PRESERVE
DO INSERT INTO log VALUES (1);

(think cron)

And:

CREATE EVENT e
ON SCHEDULE AT ‘2006-01-01 03:00:00′
ON COMPLETION NOT PRESERVE
DO OPTIMIZE TABLE foo;

(think at)

The server variable “event_scheduler” has to be set to 1 for these to work.
