Dear all,

I have one confusion regarging production rules 

suppose i have production rule as follows

expression :addingexpression;

addingexpression : IDENT  (DOT! IDENT)* | DOT CONTAINS^

now the probelm is that the first possibitlty god executed and not the 2nd one as CONTAINS is a key word but a also a valid identifier.and as a result first possiblity is always executed not the 2nd one, is there is any way to assign some perority to these rules so that it should check for the 2nd one as well.

Regards.

Muhammad.
