about freeing memory from xerces

[林 子芯 <mi...@hotmail.com>]

Hi
   i suppose this is a fairly common question, but i was wandering how i 
could handle the memory leaks in the MFC application i wrote. In this 
application i have included xalan, responsible for both xslt and DOM 
manipulation (the xerces part). At present i have included the 
initialisation at the very beginning of the program. here when an xml file 
is loaded, i have created an XalanParsedSource and a DOM_Document of the 
xml document in memory. both of which are in use throughout the program. in 
one of my module, i will need to clone the DOM_document, and preform some 
operations with it. and i was wondering how do i free all memory associated 
with this operation that was being held by the library but without killing 
off the originial document? to do so, do i have to have this operation in a 
separate thread from the main thread (the one holds the originial 
DOM_document) if so, how could i access the originial DOM_Document node 
from the new thread?

any feedback will be a great help for me

Many thanks

Regards
Kit

p.s. sorry about the dupilcation,I do not know which is the more appropiate 
list to put it into
