You want to test whether onClick is empty or onClick doesn't exist? then 
not(onClick='') is the false expression.

Or in other words:
test=" A or not(A)" is always true.

The second part should be "not(onClick)" (without  ='', because you 
would have again boolean in it).

But there is a shorter way too:

either

test="normalize-space(onClick)" (whitespaces are removed)

or

test="string(onClick)" (empty onClick but with whitespaces won't be ignored)

I think normalize-space(onClick) is the right one.
