Validating XML with XSD and DOM Parser
Hi everyone,
I'm trying to validate get the DOM parser to validate an XML instance
through an XSD file, though, I'm not really sure as to how to do
this...
I've Googled quite a bit, but I think I'm looking in the wrong direction.
XSD file: http://slexy.org/view/s2iGvEBQAU
Relevant code: http://slexy.org/view/s2c2p1D8HG
Could you point me in the right direction ? Any help is appreciated, really.
Best regards,
S.

You're right, I've simply copied it from old buggy code (I'm rewriting
my app from scratch, so it's temporary shattered and I had to refer to
the test one).
My pleasure!

Awesome !
Thanks for your help.
This is what I ended up with, the code you provided had a few memory
leaks, but it helped out a whole bunch ! Thank you so much !

Hi, I had the same problem and I solved it in this way:
--- code starts ---
XMLDOMErrorReporter* errReporter_;
XercesDOMParser* parser_;
errReporter_ = new XMLDOMErrorReporter();
parser_->setErrorHandler(errReporter_);
parser_->setValidationScheme(XercesDOMParser::Val_Always);
parser_->setDoSchema(true);
parser_->setDoNamespaces(true);
parser_->setDoValidation(true);
parser_->setValidationSchemaFullChecking(true);
parser_->setIncludeIgnorableWhitespace(false);
--- code ends ---
where the XMLDOMErrorReporter object inherits from ErrorHandler, for
example in my case:
--- code starts ---
class XMLDOMErrorReporter : public ErrorHandler {
private:
bool sawErrors;
public:
XMLDOMErrorReporter() : sawErrors(false) { }
~XMLDOMErrorReporter() { }
void
warning(const SAXParseException& e)
{
std::cerr << "-- WARNING [DOM Parser] --" << std::endl;
std::cerr << "message: " << XMLString::transcode(e.getMessage()) <<
std::endl;
std::cerr << "file: " << XMLString::transcode(e.getSystemId()) <<
std::endl;
std::cerr << "line: " << e.getLineNumber() << std::endl;
std::cerr << "column: " << e.getColumnNumber() << std::endl;
}
void
error(const SAXParseException& e)
{
sawErrors = true;
std::cerr << "-- ERROR [DOM Parser] --" << std::endl;
std::cerr << "message: " << XMLString::transcode(e.getMessage()) <<
std::endl;
std::cerr << "file: " << XMLString::transcode(e.getSystemId()) <<
std::endl;
std::cerr << "line: " << e.getLineNumber() << std::endl;
std::cerr << "column: " << e.getColumnNumber() << std::endl;
}
void
fatalError(const SAXParseException& e)
{
sawErrors = true;
std::cerr << "-- FATAL ERROR [DOM Parser] --" << std::endl;
std::cerr << "message: " << XMLString::transcode(e.getMessage()) <<
std::endl;
std::cerr << "file: " << XMLString::transcode(e.getSystemId()) <<
std::endl;
std::cerr << "line: " << e.getLineNumber() << std::endl;
std::cerr << "column: " << e.getColumnNumber() << std::endl;
}
void
resetErrors()
{
sawErrors = false;
}
bool getSawErrors() const
{
return sawErrors;
}
};
--- code ends ---
The XSD file that should be used for validation in specified in the XML
instance, for example:
--- code starts ---
<?xml version="1.0" ?>
<visor xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="visor.xsd">
...
</visor>
--- code ends ---
Hope this helps!
Best regards.
