Description:
------------
http://www.php.net/manual/en/function.serialize.php says that built-in objects can't be serialized.

This also means that SimpleXML objects can NOT be stored in the Memcached server since PHP automatically (un)serializes content stored/retrieved to/from Memcached.

What happens is that hundreds of "Node does not exist"-warnings are reported by the memcached-api (via unserialize) when trying to retrieve the SimplXML object.

Being able to easily and efficiently cache SimpleXML with Memcached would be tremendously helpful.

There is no way to store internal data structures as text.

I guess SimpleXML employs a lot of referencing pointers for performance reasons which makes it not possible to serialize without some intermediary which would do a sort of "memblock" with relative pointers/indexes ? Such a intermediary layer for serializing would mean a lot of work, I guess.

Or perhaps the performance gain on serializing the SimpleXML object with such translation neccessary would be minimal compared to reparsing an XML representation ? Hmmm ...
