Beautiful Soup is a Python library for navigating and searching HTML or XML that you already have. It turns markup into a tree of tags and text, so code can find an element by tag, attribute, or text without walking through the document by hand.<\/p>\n\n\n\n

What It Does (and What It Doesn’t)<\/h2>\n\n\n\n

Beautiful Soup parses a response body; it does not fetch the page or run its JavaScript. A common setup is to retrieve HTML with an HTTP client, pass the response text to BeautifulSoup<\/code>, then select the fields you need. If a value appears only after client-side JavaScript runs, the original HTML may not contain it.<\/p>\n\n\n\n

For example, given a page with <h1 class=\"title\">Books<\/h1><\/code>, you could find the heading with soup.find(\"h1\", class_=\"title\")<\/code> and read its text with .get_text(strip=True)<\/code>. The selectors are part of the library; the network request is a separate step.<\/p>\n\n\n\n

Choosing a Parser<\/h2>\n\n\n\n

Beautiful Soup provides one interface for several parser backends, including Python’s built-in html.parser<\/code>, lxml<\/code>, and html5lib<\/code>. They may build different trees from malformed markup. If your extraction depends on how broken HTML is repaired, name the parser explicitly and use the same one in each environment.<\/p>\n\n\n\n

The library is a good fit for modest parsing tasks and scripts where readable code matters. For a large crawl, the request scheduler, concurrency, retries, and storage usually need their own tools. Parsing with Beautiful Soup alone does not provide those pieces.<\/p>\n\n\n\n
