In general, XMLPlatformUtils::Terminate() should not be called from within a catch statement. * * Revision 1.21 2003/05/30 09:36:36 gareth * Use new macros for iostream.h and std:: issues. * * Revision 1.20 2002/04/17 20:18:08 tng * [Bug 7493] The word "occured" is misspelled and it is a global error. * * Revision 1.19 2002/02/01 22:41:17 peiyongz * sane_include * * Revision 1.18 2001/10/29 17:02:57 tng * Fix typo in samples. * * Revision 1.17 2001/10/25 15:18:33 tng * delete the parser before XMLPlatformUtils::Terminate. * * Revision 1.16 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 1.15 2001/08/01 19:11:01 tng * Add full schema constraint checking flag to the samples and the parser. * * Revision 1.14 2001/05/11 13:24:58 tng * Copyright update. * * Revision 1.13 2001/05/03 16:00:21 tng * Schema: samples update with schema * * Revision 1.12 2000/06/16 20:25:43 rahulj * Add the -v=always option to force validation checking. Need this * option for running the conformance tests. * * Revision 1.11 2000/05/31 18:36:26 rahulj * Matched the command line options supported by DOMPrint. * * Revision 1.10 2000/04/12 22:58:27 roddey * Added support for 'auto validate' mode. * * Revision 1.9 2000/04/06 19:09:51 roddey * Some more improvements to output formatting. Now it will correctly * handle doing the 'replacement char' style of dealing with chars * that are unrepresentable. * * Revision 1.8 2000/04/05 00:20:32 roddey * More updates for the low level formatted output support * * Revision 1.7 2000/03/28 19:43:11 roddey * Fixes for signed/unsigned warnings. New work for two way transcoding * stuff. * * Revision 1.6 2000/03/03 01:29:31 roddey * Added a scanReset()/parseReset() method to the scanner and * parsers, to allow for reset after early exit from a progressive parse. * Added calls to new Terminate() call to all of the samples. Improved * documentation in SAX and DOM parsers. * * Revision 1.5 2000/03/02 19:53:49 roddey * This checkin includes many changes done while waiting for the * 1.1.0 code to be finished.
