Jun 1, 2025June 2025: Strengthened data integrity and scraping resilience for topmonks/hlidac-shopu. Implemented precise price extraction for Pilulka by updating the CSS selector to target .product-price-container .product-card-price__old, ensuring the old price is captured, and adapted Hornbach data parsing to a non-standard script tag (window.pushTrackingInfo) so SKU, title, price, and image URL are retrieved when JSON-LD is unavailable. These fixes reduce data gaps, improve pricing history accuracy, and strengthen downstream analytics for business decisions. Demonstrated technologies include CSS selector targeting, DOM parsing, and fallback script-tag parsing in scraping pipelines.
