Hello Fellow Monks, I am trying to use Parse::RecDescent to parse Sql as well. I am trying to parse the sql into (placeholder / comment). Basically if I have 'select * from foo where bar = ? --This is a comment', I want to capture the 'select * from foo where bar = ?' and then '--This is a comment'. Here is the grammar, 

    $parser = new Parse::RecDescent (q{
              startrule : PlaceHolder Comment | PlaceHolder

              Comment : DD_Style

              DD_Style : m{(\s+?--.*$)}
                         { print "Comment  : \n\t", $item[1], "\n\n" }

              PlaceHolder : Xopen | Sprintf

              Sprintf : /.*=\s+?%s.*?/
                        { $item[1] =~ s{%s}{%%s}g; 
                          print "After  : \n\t", $item[1], "\n\n" }
              Xopen   : /.*=\s+?\?.*?/
                        { $item[1] =~ s{\?}{%s}g; 
                          print "After  : \n\t", $item[1], "\n\n" }

    }) unless $parser;

I set RD_TRACE on and see that is matches, Select name from foo_name where id = ? , but does not match the '--This is a Comment' I know I am missing something obvious, but I can't find it.

Any help would by much appreciated!
