- *
- * Revision 1.21 2002/07/17 18:58:36 tng
- * samples update: for testing special encoding purpose.
- *
- * Revision 1.20 2001/11/13 13:22:35 tng

- * delete the parser before XMLPlatformUtils::Terminate.
- *
- * Revision 1.17 2001/10/19 19:02:43 tng
- * [Bug 3909] return non-zero an exit code when error was encounted.
- * And other modification for consistent help display and return code across samples.
- *
- * Revision 1.16 2001/08/15 12:41:04 tng
- * Initialize the fURI array to zeros, in case, some compilers like AIX xlC_r doesn't reset the memory.
- *

- *
- * Revision 1.6 2000/05/09 00:22:29 andyh

- * as part of this.)
- *
- * Revision 1.5 2000/03/03 01:29:31 roddey
- * Added a scanReset()/parseReset() method to the scanner and
