Hi Axel,
Thanks a lot. When I added following release statements (both are
required) it worked fine.
XMLString::release(&xXml);
XMLString::release(&pChar);
Delete of the variables did not work and hence I though the leak is
within the writeToString method.
Thanks again
Biju

Subject: [jira] Commented: (XERCESC-1433) Memory leak with WriteToString

Axel Weiss commented on XERCESC-1433:
-------------------------------------
Hi Biju,
I guess you forgot to release the transcoded string (which is your
variable pChar). So your routine itself leaks. Then, you can't make any
statement about the behaviour of DOMWriter::writeToString().
Cheers,
Axel

> 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.
