In web scraping, identifying and extracting values situated between two distinct HTML elements is a nuanced task that demands precise tools. BeautifulSoup, with its robust parsing capabilities, offers the find_all() and find_next_siblings() methods as effective solutions for such scenarios. These methods enable developers to meticulously navigate the document tree, ensuring that data retrieval is both accurate and comprehensive. This technique proves essential in extracting contextually relevant data that is not directly accessible through simpler selection methods. Enhancing your web scraping endeavors with a web scraping API can significantly amplify your project’s efficiency and output quality. These APIs are tailor-made to handle sophisticated data extraction challenges, facilitating seamless access to structured data from the web. By leveraging the synergies between BeautifulSoup’s detailed parsing functions and the power of a specialized web scraping API, you can unlock new levels of precision and scalability in your data extraction projects.

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 == "h2":  # iterate through siblings until separator is encoutnered
    blocks[heading.text] = values

  'heading 1': ['paragraph 1', 'paragraph 2'], 
  'heading 2': ['paragraph 3', 'paragraph 4']
