This implementation (code below ) leaks memory on solaris (when we call it
serveral times) with xerces 2.7 and also xerces 2.8 , does anyone see a
problem with it ...
if we remove the DOMDocument importNode function call it stops leaking ..We
are especialy interested in fixing this with xerces 2.7
Also NOTE : we do release the importing document at the end but that does not
free up the memory either.
All help is appreciated .
Thanks
