Re: Possible mem leak on getElementsByTagName

[Tinny Ng]

I think you've found some valid leaks  .... Can you please open a bugzilla bug to track this problem (see http://xml.apache.org/xerces-c/bug-report.html)?   I will update you once the fix is ready.

Thanks!

My memory manager is complaining that getElementsByTagName() is causing
couple of memory leaks. The archive suggests that there have been fixes for
similar memory leaks
(http://marc.theaimsgroup.com/?l=xerces-c-dev&m=100212612816886&w=2). I was
under the impression that those changes made it into 1.6.0 release?

My understanding of iDOM interface was that there is no need to free any of
these internal structures and they will be freed when the document is
released. Am I missing anything? I have included some details of my
environment and also call stacks as reported by the memory manager.

Thanks,
