What is Data Extraction (“SQL for the Web”)🔹 Core IdeaData extraction is about selecting exactly what you want from a web page—just like SQL queries select rows from a database.Using tools like Beautiful Soup, you can: Target specific elements Extract clean text Automate structured data collection 👉 Key Insight The power is not in scraping everything— it’s in extracting only what matters2. Understanding HTML Structure🔹 The DOM Tree Concept Web pages are structured like a tree Elements have: Parents Children Siblings 👉 Example: Title $10 3. CSS Selectors (Your First Tool)🔹 Basics Tag → div Class → .price ID → #main 🔹 Combining Selectorssoup.select(\"div.product span.price\") 👉 This means: Find span.price Inside div.product 🔹 Why CSS is Powerful Simple and readable Fast to write Works directly in browsers 4. XPath (Advanced Targeting)🔹 What is XPath?Use XPath Treats HTML as a navigable tree More flexible than CSS 🔹 Key Syntax //div → find anywhere /div → direct child [@class=\"price\"] → filter by attribute 🔹 Example//div[@class=\"product\"]//span[@class=\"price\"] 🔹 When XPath Wins Complex structures Conditional logic Traversing up/down the tree 5. CSS vs XPath (Quick Comparison)FeatureCSSXPathEase of useEasyMediumPowerModerateHighReadabilityHighLowerComplex queriesLimitedStrong👉 Rule of Thumb Start with CSS Switch to XPath when needed 6.
