First of all, thanks for your answer Jim.
I have try your way of gathering attributes and it's working perfectly!
Thanks again.
But, I've try your :

predicat:    elementaryPredicat (^logicalOperator elementaryPredicat)*;

and I've got a syntax error (unexpected token ^)
Any idea how to do this ?

Thanks.
G.
