Hi,
Here is the steps you may give a try.
1. Upgrade to XercesC2_5_0 and see if it still leaks.
2. Does a memory tool identify the memory leakage, or you observe
the memory growth?
3. If it is the memory tool, which point it says the leakage
happen (besides the allocation of the memory)?
4. Modify the function
std::string GetXmlStringNew(DOMNode *pNode)
{
std::string sXML="";
//don't call DOMWriter
return sXML;
}
then see if it leaks.
5. Assuming you are using the DOMBuilder to parse your document
and get the pNode, you may need call resetDocumentPool() to
clear the memory allocated.
Rgds,
PeiYong

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;
}
