@miran, Thanks a lot. Great help. By using nested for loops, i can get the 
identifier and value individually. So this is my assumption now. Please correct 
me if i am wrong. 
    
    
    for row in body :
        result.add(nnkDotExpr(newIdentNode(obj.repr), newIdentNode(i.repr)))
    
    
    Run

But i got error message. - Undeclared routine nnkDotEcpr. Ok, then there might 
be a proc to create new dot expression.
