XSL schema in (char*) form instead of saved in file

[evangeline <ev...@gmail.com>]

Hi...

How can I pass the whole already read schema (char *) to X function, instead
of passing the filename to setExternalNoNamespaceSchemaLocation(filename)... 

So what I want to know is the name of X function I can use. 

Thanks

Evangeline, maybe you are asking about how to transcode the grammar  
document?
Possibly the easiest way is to use a MemBufInputSource for your  
grammar, rather than to transcode it.

//Your Grammar
	char* my_grammar="<.....>"
	const XMLCh my_namespace[]= {'h','t',[your namespace here],chNull};

//First set up the implementation and the parser...
	const XMLCh impltype[]= {'L','S',chNull};
	impl = DOMImplementationRegistry::getDOMImplementation( impltype );
	DOMLSParser* parser = ((DOMImplementationLS*)impl)- 
 > 
createLSParser 
(DOMImplementationLS 
::MODE_SYNCHRONOUS,NULL,XMLPlatformUtils::fgMemoryManager);
	DOMConfiguration* dc = parser->getDomConfig();
	dc->setParameter(XMLUni::fgXercesSchema, true);	
	dc->setParameter(XMLUni::fgXercesCacheGrammarFromParse, true);		
	dc->setParameter(XMLUni::fgXercesUseCachedGrammarInParse, true);		
	dc->setParameter(XMLUni::fgDOMValidate, true);
	
//load the grammar for future documents.
	XMLByte* graw = (XMLByte*)(my_grammar);
	DOMLSInput* inp = ((DOMImplementationLS*)impl)->createLSInput();	
	MemBufInputSource* mem = new MemBufInputSource(graw,  
strlen(my_grammar), my_namespace);
	mem->setCopyBufToStream(false);
	inp->setByteStream(mem);
	inp->setEncoding(XMLUni::fgUTF8EncodingString);
	parser->loadGrammar(inp, Grammar::SchemaGrammarType, true);
	
//Now you can use the parser to load up documents and validate them  
against your grammar.

You will also need to make sure that your document's root elements are  
declared with an xmlns attribute.

Alberto, does that look right to you?
Isn't there a sample for this?

	Ben.

In this case you usually have two choices: a) use loadGrammar to load 
and cache the schema using your char* as source, and then force 
validation on and turn on 'use cached grammars' before parsing your XML 
or b) use setExternalNoNomespaceSchemaLocation to point to a 
non-existent path and use an EntityResolver to trap the attempt to load 
that file in order to provide the char* to the parser.
