Validation against schema buffer

[Sharma, Gaurav]

Hi All,



Can anyone provide an example of how validation can be performed against schema 
loaded in any string buffer. I have tried various optiona but I am not getting 
any success.

What I am trying to do is:



fstream in("my.xsd");



string s, line;

while(getline(in, line))

      s += line;



XMLPlatformUtils::Initialize ();

MemoryManager* mm = new MemoryManagerImpl();

XMLGrammarPool* gp = new XMLGrammarPoolImpl(mm);



XercesDOMParser* parser = NULL;



parser = new XercesDOMParser(0, XMLPlatformUtils::fgMemoryManager, gp);

parser->setCreateCommentNodes(false);

parser->setDoNamespaces(true);

parser->setValidationScheme(XercesDOMParser::Val_Always);

parser->setDoSchema(true);

parser->setValidationSchemaFullChecking(true);

parser->setIncludeIgnorableWhitespace(false);

parser->cacheGrammarFromParse(true);

parser->useCachedGrammarInParse(true);

parser->setLoadSchema(true);

parser->setHandleMultipleImports(true);



MemBufInputSource mem_buf((XMLByte*)s.c_str(),

                              strlen(s.c_str()),

                              "fake_buf",

                               false);







if(!parser->loadGrammar(mem_buf, Grammar::SchemaGrammarType, true)) // Grammer 
loads without error

      return -1;



delete parser;


parser = new XercesDOMParser(0, XMLPlatformUtils::fgMemoryManager, gp);
parser->setCreateCommentNodes(false);
parser->setDoNamespaces(true);
parser->setValidationScheme(XercesDOMParser::Val_Always);
parser->setDoSchema(true);
parser->setValidationSchemaFullChecking(true);
parser->setIncludeIgnorableWhitespace(false);
parser->cacheGrammarFromParse(true);
parser->useCachedGrammarInParse(true);
parser->setLoadSchema(true);

parser->setHandleMultipleImports(true);


parser->parse("my_xml.xml");     // Here parsing fails

if(parser->getErrorCount() > 0)

      return -1;



Kindly suggest me what am I doing wrong.



With Best Regards
