How to select values between two nodes in BeautifulSoup and Python?

When web scraping, sometimes the values we want are located between two known HTML elements. To extract them we can use find_all() and find_next_siblings() methods:

import bs4
soup = bs4.BeautifulSoup("""
<h2>heading 1</h2>
<p>paragraph 1</p>
<p>paragraph 2</p>
<h2>heading 2</h2>
<p>paragraph 3</p>
<p>paragraph 4</p>
""")

blocks = {}
for heading in soup.find_all("h2"):  # find separators, in this case h2 nodes
    values = []
    for sibling in heading.find_next_siblings():
        if sibling.name == "h2":  # iterate through siblings until separator is encoutnered
            break
        values.append(sibling.text)
    blocks[heading.text] = values

print(blocks)
{
  'heading 1': ['paragraph 1', 'paragraph 2'], 
  'heading 2': ['paragraph 3', 'paragraph 4']
}
