Hi Vitaly,
Thanks for the reply. I did set up an error handler, similar to
SAX2Count example. Basically my xml processing class extends the
DefaultHandler class in Xerces, and I implemented the following five
methods:
void endElement( const XMLCh* const uri,
const XMLCh* const localname,
const XMLCh* const qname);
void characters(const XMLCh* const chars, const unsigned int
length);
void startElement( const XMLCh* const uri,
const XMLCh* const
localname,
const XMLCh* const
qname,
const Attributes&
attributes);
void error(const SAXParseException& exception);
void fatalError(const SAXParseException& exception);
But when I run the code, it never enters into the methods error(...) or
fatalError(...).
Again, I know I am using a very old version 1.7.0. Is this a problem? I
don't have problem parsing correct xml files, only that the validation
part seems not working as expected.
Thanks.
Frank

You have to setting up error handler. Please try to process your xml
instance with SAX2Count sample and if it works than compare your sources
with SAX2Count sources. SAX2Count can validate against XML schema too.
Good luck !
