Re: Newbie - Parsing XML String?

[Ben Griffin <be...@redsnapper.net>]

There is an example that does that.
The code I use is something like this:

//Load a DOMDocument from a utf-8 string
const std::string xmlfile; 		//The source UTF-8 encoded xml file
DOMDocument* rslt = NULL; 	//The resulting DOMDocument
string err_message;			//For parse errors
if ( ! xmlfile.empty() ) {
	const XMLCh xml_str[] = { chLatin_X, chLatin_M, chLatin_L, chNull };
	AutoRelease<DOMLSInput> input(((DOMImplementationLS*)impl)->createLSInput()); //impl is from a getDOMImplementation
	XMLByte* xmlraw = (XMLByte*)(xmlfile.c_str());
	MemBufInputSource* mbis = new MemBufInputSource(xmlraw,xmlfile.size(), xml_str);
	mbis->setCopyBufToStream(false);
	input->setByteStream(mbis);
	input->setEncoding(XMLUni::fgUTF8EncodingString);
	try {
		rslt = parser->parse(input); //parser is a DOMLSParser*
	}
	catch (DOMLSException e) {
		Manager::transcode(e.getMessage(),err_message);		//use your preferred transcoder here
	}
	catch (DOMException e) {
		Manager::transcode(e.getMessage(),err_message);		//use your preferred transcoder here.
	}
	catch ( ... ) {
		err_message = "Some load error occured with an xml file.";
	}
	delete mbis; mbis=NULL;
}
