Biju George commented on XERCESC-1433:
--------------------------------------
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.

> Commenting out the line XMLCh *xXml =

> So I think the writeString method has the leak. Let me know whether I am

> XERCESC++ version 2.6.0. Deleting xXml also did not work out for me.
