python - How find specific data attribute from html tag in BeautifulSoup4?

Question

Is there a way to find an element using only the data attribute in html, and then grab that value?

For example, with this line inside an html doc:

<ul data-bin="Sdafdo39">

How do I retrieve Sdafdo39 by searching the entire html doc for the element that has the data-bin attribute?

Answer 1

A little bit more accurate

[item['data-bin'] for item in bs.find_all('ul', attrs={'data-bin' : True})]

This way, the iterated list only has the ul elements that has the attr you want to find

from bs4 import BeautifulSoup
bs = BeautifulSoup(html_doc)
html_doc = """<ul class="foo">foo</ul><ul data-bin="Sdafdo39">"""
[item['data-bin'] for item in bs.find_all('ul', attrs={'data-bin' : True})]
