Hello Alberto,
thanks for the confirmation!
Does this hold even for releasing memory held by DOMDocument and
XercesDOMParser pointers as well.
Also if a release/delete is called on the XercesDOMParser
pointer,is it necessary to call release/delete on the DOMDocument
pointer got from the parser pointer using a getDocument?
Hi Pranav,
if you used getDocument() to get the DOMDocument pointer, memory is
automatically released when you release the parser. If you used
adoptDocument(), you have to release both the parser and the DOMDocument.
Remember that "release the parser" could mean calling "delete" (if
you created with a "new XercesDOMParser") or calling
"parser->release()" (if you created it by using domImpl->createDOMBuilder() ).
Hope this helps,
Alberto
Thanks,
Pranav

------------------------------------------
Yes, you should call release() instead of delete, in order to be sure to
use the proper memory manager
