php markdown 转html,python转换html为markdown
目录
导读：虽然我大部分使用php生成markdown，但python库确实也比较丰富的不要不要，php composer也是参考学习python包管理，才会让php也有一种搭积木的感觉。
使用python将markdown转换成html的情况比较多，今天我们将另一个库将html转换为markdown。
html2text
安装
1.使用pip
pip install html2text #python3使用pip3
2.源码安装
如果使用的是python3将下面的python后面加一个3
git clone --depth 1 https://github.com/Alir3z4/html2text.git
python setup.py build
python setup.py install
使用
import html2text
html = "
hello https://xxx.com
"md = html2text.html2text(html)
print(md)
运行结果
**hello** https://xxx.com
高级用法
忽略链接即a标签
import html2text
text_maker = html2text.HTML2Text()
text_maker.ignore_links = True
text_maker.bypass_tables = False
html = html
text = text_maker.handle(html)
print(text)
运行结果
**hello** https://xxx.com
链接
如果将ignore_links = False 运行结果
**hello** https://xxx.com
[链接](https://xxx.com)
我们可以看到开启之后只提取文本，而关闭后变成了markdown的链接语法
