Re-loading an XML file without memory leak

[Adelino Rocha]

    Hi,

        I'm implementing a program which reads and parses an XML file when 
starts and then I would need to read same XML file again cyclicly to load the 
same file again to load any possible change.

    Summarily what I'm doing is this based on this example 
<http://www.yolinux.com/TUTORIALS/XML-Xerces-C.html> (I skipped all error 
handling, etc):

        .....
        this->xmlParser = new XercesDOMParser();
        this->xmlErrHandler = (ErrorHandler*) new HandlerBase();
this->xmlParser->setErrorHandler(this->xmlErrHandler);
this->xmlParser->setValidationScheme(XercesDOMParser::Val_Auto);
        this->xmlParser->setDoNamespaces(true);
        this->xmlParser->setDoSchema(false);

*        this->xmlParser->resetDocument();*
*        this->xmlParser->parse(fileName);**
**        xmlDoc = xmlParser->getDocument();*

       .... read XML sections here


    if I repeat the part in bold cyclicly I'm able to re-load the xml file 
successfully but I get a memory leak. Memory keeps increasing on each cycle.

    I had even tried to completely destroy the xml objects like this;

    this->xmlParser->reset();
    delete this->xmlParser;
    delete this->xmlErrHandler;
    this->xmlParser = NULL;
    this->xmlErrHandler = NULL;

    and intialize them again but still have a leak

    So my question is how can I cyclicly read an xml file without having a 
memory increase on every read and without having to almost destroy all objects 
and recreate tham back again ?

     Thanks,

        Adelino.
