请参阅：java : pdfbox 读取 PDF文件内书签 或者 python：从PDF中提取目录

请注意：书的目录.txt 编码：UTF-8，推荐用 Notepad++ 转换编码。

xml 是 python 标准库，在 D:\Python39\Lib\xml\etree

python 用 xml.etree.ElementTree 生成思维导图 Freemind（.mm）文件

编辑 txt_xml_etree_mm.py  如下

# -*- coding: utf-8 -*-

运行 python txt_xml_etree_mm.py  your_pdf_dir.txt

生成 your_pdf_dir.mm
