Hi,
This one looks complicated to me. Do you think it is ok? I read in the pdf that single rules or texts enclosed in Apostrophe are automatically provided with a tree node. I do not know if it is correct in here. Could you please help?
rangeConditionItem
:((expr1=expression ':'expr2=expression)->^(':' $expr1 $expr2)
|('='|'/='|'<'|'<='|'>'|'>=')?expr3=expression)->^(RNGCONITEM ^(SIGNS '=' '/=' '<' '<=' '>' '>=')
$expr3)
;
Best wishes,
Al
