exception using visual C++

[meng-kim <me...@mediaring.com.sg>]

I try to create a simple project to using the following code but encounter exception when the program exit.

#include <xercesc/util/PlatformUtils.hpp>
//#include <xercesc/sax/SAXException.hpp>
//#include <xercesc/sax/SAXParseException.hpp>
#include <xercesc/parsers/DOMParser.hpp>
//#include <xercesc/dom/DOM_DOMException.hpp>
//#include "DOMCount.hpp"
#include <string.h>
#include <stdlib.h>
//#include <fstream.h>
#include "iostream.h"


int main(int argc, char* argv[])
{
 XMLPlatformUtils::Initialize();

 const char*              xmlFile = "e:\\temp\\LogConfiguration.xml";

 // Instantiate the DOM parser.
 DOMParser* parser = new DOMParser;

 // And create our error handler and install it
 //DOMCountErrorHandler errorHandler;
 //parser->setErrorHandler(&errorHandler);


 parser->parse(xmlFile);
 
 
 DOM_Document doc = parser->getDocument();
    //unsigned int elementCount = doc.getElementsByTagName("*").getLength();

    // Print out the stats that we collected and time taken.
    //cout << xmlFile << ": "    << elementCount << " elems)." << endl;

    //
    //  Delete the parser itself.  Must be done prior to calling Terminate, below.
    //
    delete parser;
 parser = NULL;

 // And call the termination method
 //crush, why?????
 XMLPlatformUtils::Terminate();

 return 0;
}

logConfiguration.xml
==========================================================
<?xml version="1.0" encoding="UTF-8"?>
<LogConfiguration>
 <General>
  <filename>1.txt</filename>
 </General>
 
 <CMRCallLog>
  <PhoneNo>123</PhoneNo>
 </CMRCallLog>
 
</LogConfiguration>


When the program terminates, it will encounter exception. However, removal of XMLPlatformUtils::Terminate() fix the problems.
Why?


Thanks

After you call Terminate, you shouldn't do any work on Xerces data 
structures; but you still have a DOM_Document object on the stack, whose 
destructor will be called after the Terminate() call.
Try changing the code into

XMLPlatformUtils::Initialize();
{
    DOMParser* parser=.....
    ...
    DOM_Document doc= ....
    ...
}
XMLPlatformUtils::Terminate();
