前提：需要mammoth包~

export default NovelAnalyze;

正则分割段落

原文：
第259章 这是259内容 第262章 这是262内容 第666章 测试内容

str.replace(/\s*(第\d+章)\s*/g, "@@@$1___").split("@@@").filter(item => item).map(item => ({[item.split("___")[0]]: item.split("___")[1]}))

结果：

0: {第259章: "这是259内容"}
1: {第262章: "这是262内容"}
2: {第666章: "测试内容"}
