[xml] Ability to plug in schema validation on top libxml2 SAX parser

Thu, 03 Mar 2011 14:06:11 -0800 

Hi,

I tried using xmlSchemaValidateStream() but i get error, the snippet of the
code i writing is:

*xmlSAXHandler* saxHandler = new xmlSAXHandler();
saxHandler->initialized = XML_SAX2_MAGIC;
saxHandler->startElement = &ParseData::start_parse;
saxHandler->endElement = &ParseData::end_parse;
saxHandler->characters = &ParseData::value_parse;


ParseData pdata;
xmlParserInputBufferPtr buf = NULL;
buf = xmlParserInputBufferCreateMem(xmlstr.c_str(), int(xmlstr.length()),

XML_CHAR_ENCODING_NONE);
int ret = xmlSchemaValidateStream(ctxt, buf, XML_CHAR_ENCODING_NONE,
saxHandler,
                                                    &pdata);
if (ret == 0)
   cout<<"validated "<<endl;
else if (ret > 0)
   cout<<"validation failed"<<endl;
else
   cout<<"Some internal error while validation"<<endl;*

the return value from *xmlSchemaValidateStream() *is <0. Could you see why
it would be so?

Thanks,
Sarmishtha
