Thanks Alberto,
I used resetDocumentPool(),
But I get a run time error R6025 pure virtual function call.
When/where do you call resetDocumentPool? And where do you get the pure
virtual function call? Are you attempting to access one of the DOM tree
that you have just released?
Alberto
Thanks and regards

Hi Sree,
you should invoke resetDocumentPool(), not reset(). As for the
code you
posted previously, I noticed you were not releasing the transcoded
strings (you actually commented the call to XMLString::release): that
would be a substantial leak.
On the other hand, if you want to parse files so big, you should
investigate switching to SAX parsing.
