Hi,
indeed, each node of the parsing tree will have generic informations (such 
as the text of the symbol if any and the line on which it was found) and 
infos specific to the grammar (for instance an integer saying which 
nonterminal/terminal is the node representing). Once I would have the tree, 
the analyze on it is language specific indeed.

I also start seeing the LALR difficulties Akim is pointing to me.
