Hi!
I've encountered some strange behaviour of javacc and i can't explain
why the generated parser produces this error message. I am using
javacc-3.2 and the compiled program generates the following error
message when run on a sample HTML file:
---------
Encountered "center" at line 3, column 8.
Was expecting one of:
"A" ...
"a" ...
{...}
"caption" ...
"CENTER" ...
"center" ...
"CITE" ...
{...}
"cite" ...
{...}
"VAR" ...
"var" ...
---------
This message confuses me because the parser finds something it
expected but generates the error message anyway. This is the
.jj-source:
---------
PARSER_BEGIN(IndexList)
package IndexUpdater;
import java.util.*;
public class IndexList {
public static void main(String args[]) throws ParseException {
IndexList parser = new IndexList(System.in);
parser.Input();
}
}
PARSER_END(IndexList)
SKIP :
