Comment (by dd32):

 I'm pretty sure you'll find you can't serialize SimpleXML objects (And
 therefor, can't store in a Object Cache which WordPress uses)

 The method you'd use to store an element would be to convert it to XML (It
 has a toXML() method IIRC) and create the new object afterwards from that
 xml. However, I don't think you can pull a node out of a SimpleXML object
 either reliably, as child nodes need the context of the parents too.

 I'm not sure there's anything we can do here myself?
