Thanks for the fast answer.
The code was an attempt to isolate a memory leak, but I add the extra error
that you have pointed out, so my test were wrong.
However I found my real problem, and my lack od memory were caused by the
missing deletion of XercesDomParser object.
In a procedure A I buld a DOMDOcument from a XercesDOMParser->getDocmennt().
Then in other procedures I use the DOMDocument object and then I release it but
I didn't delete the XercesDomParser object.
It is not enough release only DOMDocuemnt to release also XercesDOMParser , is
this right ?
That's correct; if you don't release the XercesDOMParser you are not
deleting everything.
Now I keep track also of the XercesDOMParser obejct and I delete it, and I have
no more memory leak.
By the way, if I have a DOMDOcument object create using
XercesDOMParser->getDocmennt(), is there a DOMDocument obejct which return me a
reference to the original XercesDOMParser object ?
No, you cannot get the parser from the document; but you can use
adoptDocument instead of getDocument, so that you can release the parser
as soon as the parsing ends, and later release the document when you are
done with it. Otherwise, using getDocument, you must *not* release the
document because it will be automatically released when releasing the
parser.

Oggetto: Re: R: parse memory leak
Hi Enzo,
every parsed file is stored in a cache (unless you invoke adoptDocument
to decide to own its lifetime by yourself); the cache is emptied when
you call release() on the parser object. Your code doesn't release
neither the parser or the error handler; try printing the memory
allocated after you delete both objects.

I have xerces 2.7 on a redhat 7.3 and I have a memory leak of about 12

Belowe I copy the code involved.
Is there an error in the code or is this a bug ?
