Jesse Pelton commented on XERCESC-1601: --------------------------------------- I'll respond on the mailing list. It's not clear that this is a bug. > SAX2 Parser throws an uncaught xercesc_2_7::XMLValid::Codes exception when > setValidationConstraintFatal is on with enclosing xml tags > ------------------------------------------------------------------------------------------------------------------------------------- > > Key: XERCESC-1601 > URL: http://issues.apache.org/jira/browse/XERCESC-1601 > Project: Xerces-C++ > Type: Bug > Components: Validating Parser (Schema) (Xerces 1.5 or up only) > Versions: 2.7.0 > Environment: Xerces 2.7 recompiled locally > Win2K, WinXP, Win2k3 > Microsoft Visual Sutudio 7.1 in either debug or release builds > Reporter: Michel Courtine > > I implemented a xerces SAX2 parser by following IBM's recommandations in > "Make the most of Xerces-C++" found at: > http://www-128.ibm.com/developerworks/xml/library/x-xercc/ > This parser works fine with large and complex files and performs a very good > validation.
