Web scraping dynamic pages requires a browser automation tool like Playwright that executes JavaScript. Use semantic selectors over brittle CSS, apply multi-tier fallbacks for extraction, and implement comprehensive error handling with timeouts to reliably capture structured data from real-world websites.

innerText returns only visible text rendered on screen, while textContent captures all text including hidden content. Choosing correctly depends on your extraction goal: use innerText for user-visible content and textContent when you need raw HTML text regardless of display state.

Regex patterns for multi-line content require the dotall or multiline flags to match across line breaks. In Playwright scraping workflows, apply regex after extracting text to handle inconsistent formatting and whitespace variations common in real-world HTML.

Yes, semantic locators target elements by their role, label, or accessible name rather than fragile CSS class selectors. This approach is more resilient to page design changes and works better with modern web frameworks that frequently restructure the DOM.

Implement a four-tier fallback hierarchy: try your primary selector, then alternative selectors, then regex patterns, then error handlers with actionable messages. This resilience strategy handles edge cases, missing elements, and layout variations without abandoning the scrape.

Use semantic targeting for images by matching alt text, title attributes, or parent element context rather than brittle src selectors. Pair this with error handling to gracefully skip missing or broken image URLs in your scraped dataset.
