Memory leak with WriteToString
------------------------------
Key: XERCESC-1433
URL: http://issues.apache.org/jira/browse/XERCESC-1433
Project: Xerces-C++
Type: Bug
Components: DOM
Versions: 2.6.0
Environment: HP-UX 11i and compiler HP ANSI C++ B3910B A.03.52
Reporter: Biju George
Using a simple serializeDOM function and in long run shows memory leak
XERCES_CPP_NAMESPACE_USE
int serializeDOM(DOMImplementation *impl, DOMNode* node, char * strError,
char * outString) {
DOMWriter* theSerializer =
((DOMImplementationLS*)impl)->createDOMWriter();
try
{
XMLCh *xXml = theSerializer->writeToString(*node);
char *pChar = XMLString::transcode(xXml);
strcpy(outString,pChar);
}
catch (const XMLException& toCatch) {
char* message = XMLString::transcode(toCatch.getMessage());
strError = message;
XMLString::release(&message);
return FAILURE;
}
catch (const DOMException& toCatch) {
char* message = XMLString::transcode(toCatch.msg);
strError = message;
XMLString::release(&message);
return FAILURE;
}
catch (...) {
strcpy(strError, "Unexpected Exception\n");
return FAILURE;
}
theSerializer->release();
return 0;
}
Commenting out the line XMLCh *xXml =
theSerializer->writeToString(*node); will show that there is no memory leak.
So I think the writeString method has the leak. Let me know whether I am doing
something wrong or a fix for the same is available. I am using XERCESC++
version 2.6.0. Deleting xXml also did not work out for me.
