The error is in your XML. If you use the schemaLocation attribute, its value must \
consist of namespace and schema location pairs separated by spaces. To specify just \
a location use the noNamespaceSchemaLocation attribute instead of the schemaLocation \
attribute.

I implemented the following algorithm:
int main(int argC, char* argV[])
{
char* filename;
bool dtdValidate = false;
bool xsdValidate = false;
char* schemaSorgente;
char* dtdSorgente;
int i;
try
{
XMLPlatformUtils::Initialize();
}
catch (const XMLException& toCatch)
{
XERCES_STD_QUALIFIER cerr << "Si รจ verificato un errore in fase di \
inizializzazione! :\n" << StrX(toCatch.getMessage()) << XERCES_STD_QUALIFIER endl;
return 1;
}
for (i = 1; i < argC; i++) {
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::fgXercesSchemaFullChecking, true);
parser->setProperty(XMLUni::fgXercesSchemaExternalSchemaLocation,schemaSorgente);
int errorCode = 0;
try
{
XmlToTestoSAX handler(encodingName, unRepFlags);
// parser->setDocumentHandler(&handler);
parser->setErrorHandler(&handler);
parser->parse(xmlFile);
errorCount = parser->getErrorCount();
}
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;
};
but I believe there are errors. Pass the following parameters from the command line:
-xsd xml\personal.xsd xml\personal-schema.xml
The xml file input is given in the following:
<?xml version="1.0" encoding="UTF-8"?>
<?proc-inst-1 'foo' ?>
<personnel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="C:/Documents and Settings/Alessandra/Documenti/Visual Studio \
2008/Projects/XmlToTestoSAXMain/xml/personal.xsd" >
<person id="Big.Boss">
<name xml:base="foo/bar"><family xml:base="bar/bar">Boss</family> <given \
xml:base="car/bar">Big</given><?proc-inst-2 'foobar' ?></name> \
<email>chief@foo.com</email> <link subordinates="one.worker two.worker three.worker \
four.worker five.worker"/> </person>
<person id="one.worker" xml:base="/auto/bar">

When you launch the program running I get the following screen:
Fatal error at file C:\Documents and Settings\Alessandra\Documenti\Visual Studio \
2008\Projects\XmlToTestoSAXMain\xml\personal-schema.xml, line 6, char \
6
Message: schemaLocation does not contain name-space location pairs
There are errors in the file. Xml or. Xsd? Furthermore, my algorithm allows to \
validate an XML document based on a DTD or XSD supplied from the outside? Thank you. \
greetings

Hi,
Please look at the SAX2Count sample source code from the Xerces-C++
source distribution.
Good luck!
