Hi All,
I have a problem trying to parse and validate an Xml document with its dtd.
When I run the code below in a console application, it runs well and the
callback functions get called. But when the same code runs from a dll, no
callback function gets called. Any help will be greatly appreciated. This
code follows the Xerces EnumVal sample.
Regards,
Eyumotu

// Initialize the XML4C system
try

// Create a DTD validator.
DTDHandlers * dh = new DTDHandlers();

valToUse->setDocTypeHandler(dh);
SAXParser parser(valToUse);
parser.setDoValidation(true);
