Hello.
I am trying to validate a DOMDocument against a schema using an
MemBufInputSource. If the document is valid, the method returns true, as
expected. If it is invalid, it exits unexpectedly at the line I added the
comment. My code is presented below these remarks:
* [serializer] is a valid DOMWriter
* [parser] is a valid DOMBuilder
* ParseErrorHandler is simply a rename of the DOMCountErrorHandler from the
samples.
* The schema to use for validation is mentioned in the xml to validate
----------------------------------------------------------------------------------------------------------------
bool XmlDataAccess::Validate(DOMDocument* doc)
{
MemBufFormatTarget memTarget;
serializer->writeNode(&memTarget, *doc);
MemBufInputSource input(memTarget.getRawBuffer(), memTarget.getLen(), "1");
Wrapper4InputSource domWrapper(&input, false);
ParseErrorHandler errorHandler;
errorHandler.resetErrors();
try
{
cerr<<"here"; // this is outputted
parser->parse(domWrapper); // this crashes it
cerr<<"here"; // this is not outputted
}
catch (SAXException* s)
{
cerr<<"SAX Error during validation parsing"; // never gets here
return false;
}
catch (DOMException* s)
{
cerr<<"DOM Error during validation parsing"; // never gets here
return false;
}
catch (XMLException* s)
{
cerr<<"Error during validation parsing"; // never gets here
return false;
}
catch (...)
{
cerr<<"Unexpected Error"; // never gets here
return false;
}
if(errorHandler.getSawErrors())
{
cerr<<"Validation parsing failed";
return false;
}
else
{
cerr<<"Validation parsing succeeded";
}
return true;
}
----------------------------------------------------------------------------------------------------------------
//
// Initialization in the ctor
//
XmlDataAccess::XmlDataAccess()
{
static const XMLCh gLS[] = { chLatin_L, chLatin_S, chNull };
impl = DOMImplementationRegistry::getDOMImplementation(gLS);
parser =
((DOMImplementationLS*)impl)->createDOMBuilder(DOMImplementationLS::MODE_SYNCHRONOUS,
0);
parser->setFeature(XMLUni::fgDOMNamespaces, true);
parser->setFeature(XMLUni::fgXercesSchema, true);
parser->setFeature(XMLUni::fgXercesSchemaFullChecking, true);
parser->setFeature(XMLUni::fgDOMValidateIfSchema, true);
parser->setFeature(XMLUni::fgDOMDatatypeNormalization, true);
serializer = ((DOMImplementationLS*)impl)->createDOMWriter();
serializer->setEncoding( X("UTF-16") );
}

Can anyone tell what is wrong? Do you need more info?
Thank you,
Vlad
