Bug report

Dynamic properties on SimpleXMLElement don't ever return null. Even for a non-existent child, it still returns a SimpleXMLElement (with a count of 0). See https://3v4l.org/a6OFI for the proof.

Array access on SimpleXMLElement also returns SimpleXMLElement objects, not mixed

Expected output

SimpleXMLElement types instead of nullable or mixed types.
