結論

function textNodes(node) {
	const _textnodes = (childNodes) => {
		if (childNodes.length <= 0) return []
		return Array.from(childNodes)
			.map(e => (e instanceof Text ? e : _textnodes(e.childNodes)))
			.flat()
	}
	return { node: node, textNodes: _textnodes(node.childNodes) }
}

微妙にどこをどうするのか悩んだ。

結果

割と上手く行った
