CSS selectors, BeautifulSoup, a loop, a CSV export. It works perfectly. You come back three weeks later. The data is missing. The site redesigned. The class .product-price is now .price-display. Your soup.select_one(\".product-price\") returns None across all 50,000 URLs you were monitoring. This is not an edge case. It is the normal lifecycle of every production scraper. D4Vinci/Scrapling — Python web scraper that adapts when sites change, so your data collection keeps working. Scrapling is the answer to this problem. Instead of finding elements by their exact CSS class — which breaks the moment a developer renames it — Scrapling finds elements by their structural position and visual role in the document. The class name is a hint, not the whole answer. When the hint changes, Scrapling adapts. By GitHub stars: Firecrawl (131k+), Playwright (90.2k+), Crawl4AI (68.2k+), Scrapy (62.1k+). Scrapling has been growing fast precisely because it solves the problem that every scraper maintainer hates most. This guide shows you the whole library — the parsing layer (Adaptor), the killer adaptive features (find_similar, auto-generated selectors), and how Scrapling's fetchers handle real websites. Installation pip install scrapling curl_cffi curl_cffi is required by Scrapling's fetchers for TLS fingerprint impersonation. Install both together. Part 1: The Adaptor — Scrapling's HTML Parser The Adaptor is Scrapling's HTML parsing layer. Think of it as BeautifulSoup with a smarter element model and additional methods for adaptive scraping. from scrapling.parser import Adaptor html = \"\"\" <html><body> <div class=\"job-card\" data-id=\"101\"> <h3 class=\"job-title\">Senior Python Developer</h3> <span class=\"company\">Infosys</span> <span class=\"location\">Bangalore</span> <span class=\"salary\">Rs. 18–25 LPA</span> <span class=\"tag\">Python</span> <span class=\"tag\">Django</span> <a href=\"/jobs/101\" class=\"apply-btn\">Apply Now</a> </div> <div class=\"job-card\" data-id=\"102\"> <h3 class=\"job-title\">Data Scientist</h3> <span class=\"company\">TCS</span> <span class=\"location\">Hyderabad</span> <span class=\"salary\">Rs. 15–22 LPA</span> <span class=\"tag\">Python</span> <span class=\"tag\">ML</span> <a href=\"/jobs/102\" class=\"apply-btn\">Apply Now</a> </div> </body></html> \"\"\" # Create an Adaptor — pass the HTML and the source URL # The URL is used for resolving relative links and for the auto-trained model page = Adaptor(html, url=\"https://techjobs.example.com\") Selecting elements Scrapling supports CSS selectors and XPath: # CSS selectors — returns a Selectors list titles = page.css(\"h3.job-title\") print([t.text for t in titles]) # ['Senior Python Developer', 'Data Scientist'] # XPath — same return type titles_xpath = page.xpath(\"//h3[@class='job-title']\") print([t.text for t in titles_xpath]) # ['Senior Python Developer', 'Data Scientist'] # find_all by tag — like BeautifulSoup's find_all items = page.find_all(\"span\") print(f\"Found {len(items)} spans\") Getting values out # .text — the element's visible text content title_el = page.css(\"h3.job-title\")[0] print(title_el.text) # Senior Python Developer # .html — the element's outer HTML print(title_el.html) # <h3 class=\"job-title\">Senior Python Developer</h3> # .attrib — dict-like attribute access (never raises KeyError) card = page.css(\"div.job-card\")[0] print(card.attrib[\"data-id\"]) # 101 print(card.attrib.get(\"data-missing\")) # None — safe access # Link href link = page.css(\"a.apply-btn\")[0] print(link.attrib[\"href\"]) # /jobs/101 # All text in a container (concatenates all descendant text nodes) card_text = card.get_all_text(separator=\" \") print(card_text[:60]) # Senior Python Developer Infosys Bangalore Rs. 18... extract() and extract_first() These return the raw HTML string of matched elements — useful when you need to re-parse a sub-section: # extract_first() → the first match as an HTML string first_title_html = page.css(\"h3.job-title\").extract_first() print(first_title_html) # <h3 class=\"job-title\">Senior Python Developer</h3> # extract() → list of all matches as HTML strings all_price_html = page.css(\"span.salary\").extract() print(all_price_html) # ['<span class=\"salary\">Rs. 18–25 LPA</span>', # '<span class=\"salary\">Rs. 15–22 LPA</span>'] Nested selection You can run CSS selectors on individual elements, not just the whole page: jobs = [] for card in page.css(\"div.job-card\"): job = { \"id\": card.attrib.get(\"data-id\"), \"title\": card.css(\"h3.job-title\")[0].text, \"company\": card.css(\"span.company\")[0].text, \"location\": card.css(\"span.location\")[0].text, \"salary\": card.css(\"span.salary\")[0].text, \"tags\": [t.text for t in card.css(\"span.tag\")], \"link\": card.css(\"a.apply-btn\")[0].attrib[\"href\"], } jobs.append(job) for j in jobs: print(f\" [{j['id']}] {j['title']} @ {j['company']} — {j['salary']}\") print(f\" {', '.join(j['tags'])}\") Traversal # children — iterate direct child elements ul_html = \"<ul><li>Item A</li><li>Item B</li><li>Item C</li></ul>\" page2 = Adaptor(ul_html, url=\"https://example.com\") ul = page2.css(\"ul\")[0] for child in ul.children: if hasattr(child, \"text\"): print(child.text) # Item A, Item B, Item C # find_ancestor — walk up the tree with a test function html3 = \"<table><tr><td class='name'>Alice</td></tr></table>\" page3 = Adaptor(html3, url=\"https://example.com\") td = page3.css(\"td.name\")[0] tr = td.find_ancestor(lambda el: el.tag == \"tr\") print(tr.tag) # tr Part 2: The Features That Make Scrapling Different find_similar() — the adaptive core This is the feature that makes Scrapling special. find_similar() finds all elements on the page that are structurally similar to a given element — same depth, same relationship to siblings and parent, same content type — even if their CSS class has changed. html = \"\"\" <table> <tr><td class=\"name\">Alice</td><td class=\"age\">30</td></tr> <tr><td class=\"name\">Bob</td> <td class=\"age\">25</td></tr> <tr><td class=\"name\">Carol</td><td class=\"age\">35</td></tr> </table> \"\"\" page = Adaptor(html, url=\"https://example.com\") # Get only the FIRST name cell by selector first_name = page.css(\"td.name\")[0] print(\"First:\", first_name.text) # Alice # find_similar() finds the other name-like cells by structural position # — NOT by class name. If \"td.name\" becomes \"td.member-name\" tomorrow, # this still works. similar = first_name.find_similar() print(\"Similar:\", [s.text for s in similar]) # ['Bob', 'Carol'] The practical workflow this enables: identify the first example of the element you want, then call find_similar() to get all others. If the site redesigns and changes class names, find_similar() still finds them by structural position. find_by_text() — locate elements by content html = \"\"\" <div class=\"card\"> <h2>Product Overview</h2> <p class=\"desc\">A quality product designed for professionals.</p> <button class=\"cta-btn\">Buy Now</button> </div> \"\"\" page = Adaptor(html, url=\"https://example.com\") # Find an element by its exact text btn = page.find_by_text(\"Buy Now\") print(btn.text) # Buy Now print(btn.tag) # button # Find by partial text desc = page.find_by_text(\"quality product\", partial=True) print(desc.text) # A quality product designed for professionals. Auto-generated selectors — never write a selector manually again Scrapling can generate a CSS selector or XPath expression for any element it finds. Use this to discover selectors rather than hunting through DevTools: html = \"\"\" <nav class=\"main-nav\"> <ul> <li><a href=\"/\" class=\"nav-link\">Home</a></li> <li><a href=\"/pricing\" class=\"nav-link\">Pricing</a></li> <li><a href=\"/about\" class=\"nav-link\">About</a></li> </ul> </nav> \"\"\" page = Adaptor(html, url=\"https://example.com\") pricing_link = page.find_by_text(\"Pricing\") print(\"CSS selector:\", pricing_link.generate_css_selector) # body > nav > ul > li:nth-child(2) > a print(\"XPath:\", pricing_link.generate_xpath_selector) # //body/nav/ul/li[2]/a print(\"Full CSS:\", pricing_link.generate_full_css_selector) # html > body > nav > ul > li:nth-child(2) > a Use case: you're scraping a new site and aren't sure what selectors to use. Run find_by_text() on known content, then call generate_css_selector to get the precise selector to use in your production code. Part 3: Fetching Pages with Scrapling The Adaptor alone is a parser — you bring the HTML. Scrapling also ships three fetcher classes that handle the HTTP layer and return Adaptor objects directly. Fetcher — fast HTTP, no browser Fetcher uses httpx under the hood. Good for simple server-rendered pages with no anti-bot protection. from scrapling.fetchers import Fetcher fetcher = Fetcher(auto_match=True) # auto_match enables adaptive matching # fetch() returns an Adaptor object — parse it immediately page = fetcher.get( \"https://books.toscrape.com/\", timeout=20, stealthy_headers=True, # Add realistic browser headers automatically ) # Use Adaptor methods on the result titles = page.css(\"h3 a\") for t in titles[:5]: print(t.attrib.get(\"title\", t.text)) StealthyFetcher — TLS impersonation StealthyFetcher uses curl_cffi to impersonate real browser TLS fingerprints. Use this for sites that check JA3/TLS fingerprints (Cloudflare, most major e-commerce sites). from scrapling.fetchers import StealthyFetcher fetcher = StealthyFetcher(auto_match=True) page = fetcher.get( \"https://target-site.com/products\", timeout=30, # Scrapling picks a Chrome impersonation target automatically ) # Result is still an Adaptor — same API prices = page.css(\".price\") print([p.text for p in prices]) PlayWrightFetcher — full browser rendering For JavaScript-heavy sites: from scrapling.fetchers import PlayWrightFetcher fetcher = PlayWrightFetcher(auto_match=True) page = fetcher.get( \"https://spa-site.com/dashboard\", headless=True, network_idle=True, # Wait for all XHR to complete timeout=30, disable_resources=True, # Block images/fonts for speed ) # Same Adaptor API data = page.css(\".data-table tr\") Part 4: The auto_match System auto_match=True is Scrapling's most powerful feature — and the one that requires a bit of explanation. When you use auto_match, Scrapling stores a fingerprint of each element you extract — not just its CSS class, but its position in the DOM tree, its relationship to sibling elements, its text content pattern, and other structural signals. On subsequent runs, if the CSS class has changed, Scrapling uses this fingerprint to locate the element anyway. from scrapling.fetchers import Fetcher fetcher = Fetcher(auto_match=True) # First run: Scrapling fetches the page and learns element fingerprints page = fetcher.get(\"https://example.com/products\") # You select by CSS class — Scrapling memorises the element price = page.css_first(\".product-price\") print(price.text) # Rs. 1,299 # Three weeks later: site redesigns, \".product-price\" → \".price-tag\" # Scrapling's auto_match finds the element by structural fingerprint # Even though the CSS class changed, it still returns the right element page2 = fetcher.get(\"https://example.com/products\") price2 = page2.css_first(\".product-price\") # Old selector still works! print(price2.text) # Rs. 1,299 — correct even after the redesign This is the real promise of Scrapling: selectors that survive redesigns. Part 5: A Complete Production Scraper with Scrapling Let's build a complete working scraper that uses Scrapling's full feature set: # scrapling_full_example.py import asyncio import pandas as pd from scrapling.parser import Adaptor # We use Adaptor with pre-fetched HTML for this example # In production, replace with StealthyFetcher.get() or PlayWrightFetcher.get() SAMPLE_PAGE_HTML = \"\"\"<!DOCTYPE html> <html> <head><title>Tech Products — Store</title></head> <body> <h1 class=\"page-heading\">Latest Products</h1> <div class=\"product-grid\"> <article class=\"product-card\" data-sku=\"WGT-001\"> <h2 class=\"product-name\">Wireless Keyboard Pro</h2> <div class=\"pricing\"> <span class=\"current-price\">Rs. 3,499</span> <span class=\"original-price\">Rs. 4,999</span> <span class=\"discount-badge\">30% off</span> </div> <ul class=\"feature-list\"> <li>Bluetooth 5.2</li> <li>Multi-device pairing</li> <li>12-month battery</li> </ul> <div class=\"meta\"> <span class=\"brand\">Logitech</span> <span class=\"rating\">4.6 ★</span> <span class=\"reviews\">2,841 reviews</span> </div> <a href=\"/products/WGT-001\" class=\"product-link\">View Product</a> </article> <article class=\"product-card\" data-sku=\"MNT-002\"> <h2 class=\"product-name\">4K USB-C Monitor</h2> <div class=\"pricing\"> <span class=\"current-price\">Rs. 28,999</span> <span class=\"original-price\">Rs. 34,999</span> <span class=\"discount-badge\">17% off</span> </div> <ul class=\"feature-list\"> <li>4K 27-inch IPS</li> <li>USB-C 90W PD</li> <li>HDMI 2.1</li> </ul> <div class=\"meta\"> <span class=\"brand\">LG</span> <span class=\"rating\">4.8 ★</span> <span class=\"reviews\">1,204 reviews</span> </div> <a href=\"/products/MNT-002\" class=\"product-link\">View Product</a> </article> <article class=\"product-card\" data-sku=\"HDS-003\"> <h2 class=\"product-name\">ANC Headphones Elite</h2> <div class=\"pricing\"> <span class=\"current-price\">Rs. 12,499</span> <span class=\"original-price\">Rs. 15,999</span> <span class=\"discount-badge\">22% off</span> </div> <ul class=\"feature-list\"> <li>Active Noise Cancellation</li> <li>40hr battery</li> <li>Hi-Res Audio</li> </ul> <div class=\"meta\"> <span class=\"brand\">Sony</span> <span class=\"rating\">4.7 ★</span> <span class=\"reviews\">5,632 reviews</span> </div> <a href=\"/products/HDS-003\" class=\"product-link\">View Product</a> </article> </div> </body> </html>\"\"\" def scrape_products(html: str, source_url: str) -> list[dict]: \"\"\" Parse product cards from a page using Scrapling.
