Hi All,
I am using Xerces-c 2.7. I am having a problem
validating XML against a given DTD (a string).
I am using SAX2XMLReader and using loadGrammar(...) to
load the DTD. My code is something like this:
SAX2XMLReader* parser =
XMLReaderFactory::createXMLReader();
parser->setFeature(XMLUni::fgSAX2CoreValidation,
m_bValidate);
parser->setFeature(XMLUni::fgXercesDynamic, true);
parser->loagGrammar(DTDInputSource,
Grammar::DTDGrammarType);
parser->setErrorHandler(errorHandler);
parser->setContentHandler(contentHandler);
parser->parse(XMLinputsource);
I noticed that the validation is not happening,
invalid xml gets parsed without problem. However, if I
don't use loadGrammar(...), instead, I embedded the
dtd content into XML input using <!DOCTYPE ... ]>,
then the validation happens correctly.
Do I need to do some special settings? any problem
with loadGrammar(...)?
I believe you need to set the feature "use cached grammar in parse:"
http://xml.apache.org/xerces-c/program-sax2.html#use-cached
Not that if you enable the feature to cache the grammar from the parse,
this feature is automatically enabled:
http://xml.apache.org/xerces-c/program-sax2.html#cache-grammar
