antlr - How to strip quotes from a string -

i wrote simple rule match string in antlr grammar:

string    :   '"' (esc | ~["\\])* '"'    ;

actually need content of string , not quotes, required match string.

i found solution antlr 3, which published in antlr wiki. know if there solution achive same without custom code.

this should work:

string    :   '"' (esc | ~["\\])* '"'    {settext(gettext().substring(1, gettext().length()-1));}    ;

it simple removes first , last character string.
