Unless your xml input was very small you probably exceeded it's input window.
I suspect chatgpt does some summarization under the covers but otherwise it still only has a finite and fairly small lookback.

I think this is very tricky to solve conceptually (since the human authors don't have the same input event horizon problem), but it could be (and has been) papered over by making the context bigger.
