Problem with searching over Beautiful Soap object

[snippsat]

from bs4 import BeautifulSoup

html = '''\
<li>
  <span class="a-list-item">
    <span class="a-text-bold">
      Publisher
    </span>
    <span>
      Springer; 1st ed. 2020 edition (April 27, 2020)
    </span>
  </span>
</li>

<li>
  <span class="a-list-item">
    <span class="a-text-bold">
      Publication date
    </span>
    <span>
      April 27, 2020
    </span>
  </span>'''

soup = BeautifulSoup(html, 'lxml')

>>> tag = soup.find('span', class_="a-list-item")
>>> tag.find_all('span')[0].text.strip()
'Publisher'
>>> tag.find_all('span')[1].text.strip()
'Springer; 1st ed. 2020 edition (April 27, 2020)

Also remember that BS support CSS Selectors .

>>> tag = soup.select_one('span > span:nth-child(2)')
>>> tag.text.strip()
'Springer; 1st ed. 2020 edition (April 27, 2020)'

This is what i use most,as when look in browser(inspect) can copy Selector then get the path as show here automatically.
