问题
I'm having difficulty getting the proper syntax to extract the value of an attribute in Beautifulsoup with HTML 5.0.
So I've isolated the occurrence of a tag in my soup using the proper syntax where there is an HTML 5 issue:
tags = soup.find_all(attrs={"data-topic":"recUpgrade"})
Taking just tags[1]:
date = tags[1].find(attrs={"data-datenews":True})
and date here is:
<span class="invisible" data-datenews="2018-05-25 06:02:19" data-idnews="2736625" id="horaCompleta"></span>
But now I want to extract the date time "2018-05-25 06:02:19". Can't get the syntax.
Insight/help please.

You can access the attrs using key-value pair
Ex:
from bs4 import BeautifulSoup
s = """<span class="invisible" data-datenews="2018-05-25 06:02:19" data-idnews="2736625" id="horaCompleta"></span>"""
soup = BeautifulSoup(s, "html.parser")
print(soup.span["data-datenews"])
Output:
2018-05-25 06:02:19
