Complicated count() query

Hi all

I have some data like this:

<list>
	<student>
		<name>John Smith</name>
	...
	</student>
	<student>
		<name>G. Whizz</name>
	</student>
	...
</list>

and I would like to do a case-insensitive count of all "john"
occurrences. Does anyone have any idea how to do this? I'm completely
stumped.

Thanks

Zak
