Summary
In this lesson, you’ll learn about: how HTML is structured as a tree, how to turn raw pages into navigable data using Beautiful Soup, and how to extract specific elements efficiently1. Understanding the HTML Parse Tree🔹 The Structure of a Web PageEvery web page is a hierarchical tree made of nodes: Root → Children → and Siblings → elements at the same level 🔹 Key Sections → metadata (title, scripts, styles) → visible content 👉 Key Insight Scraping is really about navigating this tree intelligently2. Turning HTML into Data (Beautiful Soup)🔹 The Core ToolUse Beautiful Soup Converts raw HTML → structured Python object Makes navigation simple and readable 🔹 Why It’s Powerful Handles messy HTML Supports multiple parsers Easy to search and extract 3. Choosing the Right Parser🔹 Available ParsersParserStrengthlxmlFast and efficienthtml5libHandles broken HTML🔹 When to Use Each Use lxml → performance Use html5lib → unreliable or malformed pages 👉 Pro Insight Real-world pages are often messy → parser choice matters4. From Request to Parsed Tree🔹 Workflow Overview Send HTTP request Receive HTML Parse with Beautiful Soup Navigate and extract 🔹 Example Setupimport requests from bs4 import BeautifulSoup r = requests.get("https://example.com") soup = BeautifulSoup(r.text, "lxml") 5. Extracting Text Content🔹 Headers & Paragraphstitle = soup.h1.string paragraph = soup.p.string 👉 Use Case Blog titles Article content Product descriptions 6. Extracting Attributes (Links & Images)🔹 Accessing Attributeslink = soup.a["href"] image = soup.img["src"] 👉 What You Can Extract URLs Image sources Metadata 7. Working with CSS Classes🔹 Finding Elements by Classitems = soup.find_all("div", class_="product") 🔹 Important Note Classes can be multi-valued 👉 Beautiful Soup handles this intelligently…
