The following code is the only final version of the algorithm, which returns as
a mandate running errorCount = 6, I have deliberately altered the pattern. Xsd
so that it is different from the xml file. How do I get my printing errors that
occurred during the parsing? Thank you.
int main(int argC, char* argV[])
{
char* filename;
bool dtdValidate = false;
bool xsdValidate = false;
static char* schemaSorgente=0;
char* dtdSorgente;
int i;
try
{
XMLPlatformUtils::Initialize();
}
catch (const XMLException& toCatch)
{
XERCES_STD_QUALIFIER cerr << "Si è verificato un errore in fase di
inizializzazione! :\n"
<< StrX(toCatch.getMessage()) << XERCES_STD_QUALIFIER endl;
return 1;
}
for (i = 1; i < argC; i++) {
//Argomenti in posizione 0 non ci interessa in quanto è relativo al
progetto. I paramentri
//passati in input sono 4 ma è necessario analizzare solo quelli in
posizione 1-2-3
if (!strcmp(argV[i], "-dtd")) {
dtdValidate = true;
dtdSorgente = argV[++i];
} else if (!strcmp(argV[i], "-xsd")) {
xsdValidate = true;
schemaSorgente = argV[++i];
}}
xmlFile = argV[3];
int errorCount = 0;
SAX2XMLReader* parser = XMLReaderFactory::createXMLReader();
parser->setFeature(XMLUni::fgSAX2CoreNameSpaces, true);
parser->setFeature(XMLUni::fgSAX2CoreValidation, true);
parser->setFeature(XMLUni::fgXercesDynamic, false);
parser->setFeature(XMLUni::fgXercesSchema, true);
parser->setFeature(XMLUni::fgXercesSchemaFullChecking, true);
int errorCode = 0;
try
{
parser->setContentHandler(&handler);
parser->setErrorHandler(&handler);
parser->setEntityResolver(&handler);
parser->parse(xmlFile);
errorCount = parser->getErrorCount();
cout << "Numero errori: "<<errorCount;
}
catch (const OutOfMemoryException&)
{
XERCES_STD_QUALIFIER cerr << "OutOfMemoryException" <<
XERCES_STD_QUALIFIER endl;
errorCode = 5;
}
catch (const XMLException& toCatch)
{
XERCES_STD_QUALIFIER cerr << "\nAn error occurred\n Error: "
<< StrX(toCatch.getMessage())
<< "\n" << XERCES_STD_QUALIFIER endl;
errorCode = 4;
}
if(errorCode) {
XMLPlatformUtils::Terminate();
return errorCode;
}
//
// Delete the parser itself. Must be done prior to calling Terminate,
below.
//
delete parser;
// And call the termination method
XMLPlatformUtils::Terminate();
if (errorCount > 0)
return 4;
else
return 0;
};

Hi Alessandra,
the location of the file should be a valid URI, so you should replace
spaces with %20
