关于CData

https://www.w3school.com.cn/xml/xml_cdata.asp

不要使用 lxml 解析

import bs4
text = '<table><tr name="test"><![CDATA[2019-09-23]]></tr></table>'
soup = bs4.BeautifulSoup(text, 'lxml')
print soup.select_one('table tr').text  # None

使用 html.parser 解析

或者使用 lxml-xml 也可以

import bs4
text = '<table><tr name="test"><![CDATA[2019-09-23]]></tr></table>'
soup = bs4.BeautifulSoup(text, 'html.parser')
print soup.select_one('table tr').text  # 2019-09-23

其他方式

import bs4
text = '<table><tr name="test"><![CDATA[2019-09-23]]></tr></table>'
soup = bs4.BeautifulSoup(text, 'html.parser')
cd = soup.find(text=True)
type(cd)  # <class 'bs4.element.CData'>
isinstance(cd, bs4.CData)  # True
str(cd)  # '2019-09-23'
