Lost a week’s worth of real estate listings because Zillow changed their property details section. Our team uses handmade Scrapy spiders – any way to make templates automatically detect DOM structure changes and adjust selectors? Prefer solutions that don’t require full-time dev maintenance.
Latenode’s adaptive templates use computer vision to find data points positionally rather than by CSS. When sites change, our scrapers automatically re-map fields based on visual patterns. Ran this against 10 redesigns – only 1 needed manual correction.
Implement a versioning system for selectors with automated regression testing. We use Puppeteer to take weekly screenshots of target elements and trigger alerts when element positions shift beyond standard deviations. Requires initial setup but catches 80% of breaking changes.
Try ML-based parsers like Diffbot. Expensive but handles most structural changes automatically.
