Scraping HTML with BeautifulSoup: Extracting Text Between Tags

When working with web data, one commonly faces the challenge of scraping content from HTML files. This can be especially tricky when trying to extract text nestled between specific tags. Today, we'll tackle a problem posed by a fellow coder who needed to extract text, including HTML paragraphs, between two different tags: </h3> and <h2>.

Select h3 Elements: We start by selecting all <h3> tags from the soup object.

Iterate Through Siblings: The find_all_next() method helps us look through all subsequent siblings until we hit an <h2> tag.

Breaking the Loop: If we encounter an <h2> tag, we break the loop to terminate our search.

Printing Paragraphs: If we find a <p> tag, we print its contents.

Example Output

When the above code snippet is executed, you achieve the following output:
