Can't you just put a condition before

parent.removeChild(node);

such as

if (parent.isSameNode(node.getParentNode()))

Then it would only remove a direct child of the given parent.

Answer 2

parent.removeChild(node) is throwing a NOT_FOUND_ERR because node is not a child of parent. I see that node comes from getElementsByTagName which might not be an immediate child of parent. It could be anywhere under parent.

nodeToBeRemoved.getParentNode().removeChild(nodeToBeRemoved);

Answer 4

This is because when you are doing parent.removeChild(node), parent is not necessarily the parent of the node because getElementsByTagName() is doing a recursive search.
