Re: Append OnClick-Script to MathML-Tags

I copy your mail to the mozilla mathml list since I suppose it was your 
intention (I'm not sure your problem is really mathml-specific though, 
and you can certainly find more help elsewhere).

I've not really read your code in details, but your function load(el) 
attach an "onclick"  listener to the element el. So you must call it 
after having loaded the page (for each element you want to track), not 
when the user clicks on the MathML elements (and anyway I don't think 
you can use the "onclick" attribute on them).
