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.

Thanks for your reply, but still the memory consumption has not come
down. Is there any way i can reuse DOMDocument variable also like in
the following snippet...
do
{
/*create a source file */
parser_.parse(source); //parser_ is a XercesDOMParser object
xercesc::DOMDocument* xmlDoc = parser_.getDocument() ;
/*How to release the memory allocated to the DOMDocument pointer*/
/*parse the file source*/
/*delete the source file*/
/*I used the function which you suggested*/
parser_.reset();
/*still it takes up a lot of memory when parsing a big file*/
}while(dwbytes==bufsize);
/*some condition*/
Finally I also have one more doubt... When we use DOM, the entire file
to be parsed is brought into the memory isnt it... Now if I have to
parse a large file, say 380 MB or 1GB, we cant Bring the entire file
to the memory. So I thought it would be better to split the file into
smaller sizes and parse them bit by bit (4K long)... that is the
reason i have used create source file in the above code....
Am I in the Right path????

It looks to me like you could call the various
XercesDOMParser::reset...() and AbstractDOMParser::reset...()
methods. Or, to be paranoid and/or lazy, you could use a new
parser for each iteration.
