[FleXML-Users] Missing error detection

[Benoit G. <gu...@th...>]

Hello,

I'm trying to use flexml and I see that some error cases are not
catched. I've seen that the section 'FLEXML_FINAL' is not set in the
default skeleton so that the global error catching code is not expanded
in the generated lex file.

I can understand that since the rules are really general (and in most
cases cannot be reached) but I think that at least the all functionnal
error cases should be catched by default.

The patch I did in the flexml file is the following :

    elsif ( /^FLEXML_FINAL$/ and not $nofail ) {

      # Catch-all "real" error cases.
      for my $tag (@tags) {
        for (split ',',$states{$tag}) {
          # The error cases for end states are managed somewhere else
          if (not exists $mixed{$tag} and not ($endstates{$tag} =3D~
/$_/)) {
            print "<$_>{\n";
            print " \"<\"{Name} FAIL(\"Unexpected tag `%s'.\",
yytext+1);\n";
            print " .    FAIL(\"Unexpected CDATA `%c' in
$tag.\",yytext[0]);\n";
            print "}\n";
          }
        }
      }
    }

But I am not sur it works in all cases...

Regards,
