Hi Alessandra,
you are already setting up an error handler; you just need to be sure
that the type of the "handler" variable (that we don't see defined) has
overridden the proper virtual methods that are invoked when an error is
reported.

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

I replaced
parser->setProperty(XMLUni::fgXercesSchemaExternalSchemaLocation,schemaSorgente);
con

I no longer have the error on schemalocator but I get the following error
enable entities to open prumary C: / Documents ..... /?????d???1???. And then I
printed a series of errors such as:
-no declaration found for element personnel.
I think I can not open or find the file. xsd. What could be the problem, run
the code as a console project in VisualStudio 2008.
Any idea on the problem?

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* schemaSorgente;
char* dtdSorgente;

if (!strcmp(argV[i], "-dtd")) {
dtdValidate = true;
dtdSorgente = argV[++i];
} else if (!strcmp(argV[i], "-xsd")) {

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(&amp;amp;handler);
parser->setErrorHandler(&amp;amp;handler);
parser->parse(xmlFile);
errorCount = parser->getErrorCount();
}
catch (const OutOfMemoryException&amp;amp;)
{
XERCES_STD_QUALIFIER cerr<< "OutOfMemoryException"<<

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' ?>

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!
