Key: XERCESC-1279
Summary: Memory leak with writeToString in DOMWriter
Type: Bug

Description:
Hi All,
I have a very critical issue and we a re trying to implement this in our mission critical application..
I'm trying to use writeToString in DOMWriter using the function GetXmlString below ---->
I am getting a memory leak proportionate to the size of document been serialized.
I'm unable to free up the memory allocated .
Is it something else we need to do ensure that the leak is closed..
Kindly suggest..
std::string GetXmlString(DOMNode *pNode)
{
std::string sXML = "";
try
{
DOMImplementation* impl = DOMImplementationRegistry::getDOMImplementation(X("Core"));
// get the XML string out of the DOM
DOMWriter *theSerializer = impl->createDOMWriter();
XMLCh *xXml = theSerializer->writeToString(*pNode);
char *pChar = XMLString::transcode(xXml);
sXML = pChar;
XMLString::release(&pChar);
XMLString::release(&xXml);
delete theSerializer;
// delete impl;
// theSerializer->release();
//delete theSerializer;
}
catch(const XMLException& toCatch)
{
char *pMsg = XMLString::transcode(toCatch.getMessage());
XMLString::release(&pMsg);
}
return sXML;
}

Hi,
i also tried using this snippet ..but the memory leak is still there..
std::string GetXmlStringNew(DOMNode *pNode)
{
std::string sXML = "";
try
{
DOMImplementation* impl = DOMImplementationRegistry::getDOMImplementation(X("Core"));
// get the XML string out of the DOM
DOMWriter *theSerializer = impl->createDOMWriter();
XMLCh tempStr[100];
MemBufFormatTarget destination;
bool retVal;
try
{
retVal = theSerializer->writeNode(&destination, *pNode);
}
catch (...)
{
retVal = false;
}
//const
char *charString = (retVal ? XMLString::replicate((char*)destination.getRawBuffer()) : 0);
//delete theSerializer;
theSerializer->release();
//******************************
// std::string sRet(charString);
sXML = charString;
XMLString::release(&charString);
return sXML;
}
catch(const XMLException& toCatch)
{
char *pMsg = XMLString::transcode(toCatch.getMessage());
XMLString::release(&pMsg);
}
return sXML ;
}
//************************

Dee,
To isolate the leakage problem, I've done test on the sample, DOMPrint and there is no leakage reported from Purify.
You may start from DOMPrint as well, by changing line#494
//
// do the serialization through DOMWriter::writeNode();
//
//theSerializer->writeNode(myFormTarget, *doc);
XMLCh* strResult = theSerializer->writeToString(*doc);
XMLString::release(&strResult);
by commenting/uncommenting the release the purify will report leakage/no leakage.
Besides, can you post the leakage report from your memeor tool? thanks.
Rgds,
PeiYong
