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 ; 
} 
//************************

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; 
}
