Dr. Xerces:
I am trying to figure the best way out to handle semantic errors in
a SAXParser. I did not find how I get to the positioning information
(i.e. file,line,char position) from within a HandlerBase method
(in my case start/endElement);
In case you need a little more context, here is how I set my parser up:
----------------------------------------------------------------------------
Driver driver; // one of my own data structures
DriverXMLHandler handler(&driver); // DriverXMLHandler derives
// from SAXHandlerBase which in turn
// derives from HandlerBase
SAXParser parser;
parser.setDoValidation(true);
parser.setDocumentHandler(&handler);
parser.setErrorHandler(&handler);
try {
parser.parse(configurationFile);
}
catch (const SAXException& toCatch) {
ReportException("Error:", toCatch);
return 1;
}
catch (const XMLException& toCatch) {
String msg = String("Can't open '") + args.configurationFile + "'.";
ReportException(msg, toCatch);
return 1;
}
----------------------------------------------------------------------------
SAXHandlerBase implements error, fatalError, and warning.
DriverXMLHandler implements startElement and endElement.
it updates the Driver instance that it received upon construction
according to what is found in the file that is being parsed.
Whenever there is a semnatic error in the parsed file
DriverXMLHandler::start/endElement should report it in terms of
file and line number and go on.
----------------------------------------------------------------------------
I'd appreciate any help.
