No. Not at all. "pass" is not very informative. Neither are
"representation" and "the string". Please tell us what you mean by
"slice". What is an "item", if it's not a "node"? Try listing out the
attributes of a node, with a couple of sample values for each, and then
we might get a clue.

What makes you think that you need to save memory?

What makes you think that you could save memory by splitting whatever
it is?
