Jflex Regular expression

Question

I am trying to write a .flex file that recognises a string literal,which is a sequence of characters surrounded by double quotes. No escape characters, but I just cant get it to identify them, This is my latest attempt.

\"(\\.|[^"])*\"

Any suggestions

You could use instead

\"(.[^\"]*)\"

(\"(\\.|[^"]+)*\") {return new Token (Token.STRING, yytext());} – user2904478 Oct 21 '13 at 19:11
YYINITIAL is the inital scanning state – user2904478 Oct 21 '13 at 19:11
Simply use `\"[^\"]*\"`? – Rohit Jain Oct 21 '13 at 19:12
