[antlr-interest] how to perform exact matching during tree parsing instead of sufficient matching

[Muhammad Masoom Alam]

Dear all,

 

As mentioned in the documentation of ANTLR that it performs sufficient matches instead of exact matches.

 

But I want exact match , I have a the following lines of code

 

check_rule

            :  (#(AND #(OR somerule1) #(IMPLIES somerule2)))

            | ( #(AND somerule3) #(IMPLIES somerule4)) 

            ;

 

it doesnot work 

 

I have tried the solution as follows

 

Check_rule 

: (#(AND #(OR somerule1) #(IMPLIES somerule2)))=> (#(AND #(OR somerule1) 

#(IMPLIES somerule2)))

|

( #(AND somerule3) #(IMPLIES somerule4))  => ( #(AND somerule3) #(IMPLIES somerule4))

 

if some body can help me in this

Regards

Muhammad.
