Basically accumulate the text into a variable using an action inside the
(...)+ loop and then push the accumulation. Something like (UNTESTED):
text
@init{ String str = ""; } :
( t=(UNQUOTED_ALPHA_TEXT | DECIMAL_NUMBER) { str+=$t.text; } )+
{ stack.pushUnquotedText(str); }
;
Note that the t=(...) only works because all of the stuff inside the
(...) are Tokens (i think).
Note that any tokens that were put on the HIDDEN channel (or skip();d)
by the Lexer will not be accumulated/pushed.
Hope this helps...
