[jflex-users] Syntax error for a regex rule

[Denis W. <ddw...@gm...>]

Hi folks,
I'm new to JFlex and regex.
I get a syntax error when generate using .flex file. My .flex is sm thing
like as follows.

%%
VALUE = '"' ([^<&"] | [0-9])* '"' |  "'" ([^<&'] | [0-9])* "'"
%%
{VALUE}                      { return symbol(sym.VALUE); }


I get an error message as follows.

Reading "/home/hdd2/Acedemic/L4-S1/CS4410-CompTheory/project/Tokenizer.flex"

Error in file
"/home/hdd2/Acedemic/L4-S1/CS4410-CompTheory/project/Tokenizer.flex" (line

Can anyone give me a clue to solve this?
