Python移除Html的sytyle属性（remove attributes from HTML tags

清洗爬虫数据的时候可能会需要去掉很多word软件生成的html属性。

以下代码在python3.6环境下测试通过。

import lxml.html.clean as clean
# 需要保留的html属性
safe_attrs = set(['src', 'href', 'colspan', 'rowspan'])
cleaner = clean.Cleaner(safe_attrs=safe_attrs)
html_string = "var desc='<p><span style=\"color: #000000;\"></span></p><p align=\"center\" style=\"margin: 0.0cm 0.0cm 0.0pt;text-align: center;line-height: 30.0pt;\"><span style=\"color:
