How to find an element having an attribute of unknown value using BeautifulSoup?

Question

This is how it is done when attribute value we are looking for is known:

from bs4 import BeautifulStoneSoup
soup = BeautifulStoneSoup(html, 'html.parser')
found_elems = soup.find_all(attrs={"myattribute" : "myknownvalue"})

How do I find all elements with "myattribute" attribute, not knowing it's value?

Answer 1

If you don't know value of attribute, set it to True:

from bs4 import BeautifulStoneSoup
soup = BeautifulStoneSoup(html, 'html.parser')
found_elems = soup.find_all(attrs={"myattribute": True})
