I had a look at you problem... and I found it impossible to reproduce the
errors or warnings - this leads me to believe that something on your system(s)
is ****ed, libxml2 would a good place to start looking....
BUT,
even though I managed to retrieve the DomDocument object from the session
on the second/subsequent requests the object stored in the session did not
contain the XML string that was originally loaded.... so that
$_SESSION['dom']->saveXML() return NULL. which is not what I would expect but maybe
its correct behaviour.
anyway if you get so far as to see the same behaviour as I do you may have something
solid to report as a bug (or at least post a question here, or possibly on internals)
otherwise you're looking at refactoring you code to work around the problem
