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;
}
