I hope this helps you get started:

This may help you get started:

from bs4 import BeautifulSoup
from itertools import chain
soup = BeautifulSoup('''\
<div style="font-size: 20pt;"><span style="color: #000000;"><em><strong>"Is
today the day?"</strong></em></span></div>
<div style="font-size: 20pt;"><span style="color: RGB(0, 0,
0);"><strong><em>"Is
tomorrow the day?"</em></strong></span></div>''')

# We're going to get all the tags that specify the color, either using hex
or RGB.
# If you only want to get the span tags, just give the positional argument
'span' to
# find_all:
# for tag in chain(soup.find_all('span', style='color: #000000;'),
#                  soup.find_all('span', style='color: RGB(0, 0, 0);')):

for tag in chain(soup.find_all(style='color: #000000;'),
                 soup.find_all(style='color: RGB(0, 0, 0);')):
    try:
        print(tag.em.strong.text)
    except AttributeError:
        try:
            print(tag.strong.em.text)
        except AttributeError:
            print('ooooooh nooooo no text')
