in reply to Use Storable for storing XML::LibXML object
The problem is that an XML::LibXML node is really just a pointer to a libxml struct that lives in XS land. It has no real meaning once the DOM is disposed of.
What to do about it? Firstly, an important question. Say you've stored a node which represents a deeply nested XML element. Once you've retrieved the object from storage, should you only be allowed to query "down" from the node, or should $node->parentNode Just Work™?
