[xsl] counting nodes based on text within

["Nouwens, H.J.P." <H dot J dot P dot Nouwens at CiTG dot TUDelft dot NL>]

Hi there, can you help me?
I have a piece of xml like this. I want to convert it to al list (table) of
date, email adresses and choice. That I can do, that's easy.
Now I want to start of the page with a summary like:

number of people choose "item a" is 2
number of people choose "item b" is 1

The number of choices is limited to 5. I'm willing to duplicate a piece of
code 5 times :-) But a generic solution will surely be nicer...

Thanks!
