LLMs replace CSS selectors for resilient web scraping

A new method for web scraping uses Large Language Models (LLMs) to extract data, offering a more resilient approach than traditional CSS selectors. This LLM-powered technique focuses on the semantic meaning of content rather than its structural placement in the HTML. By defining a target JSON schema, developers can instruct LLMs to parse web pages, overcoming issues caused by dynamic class names, A/B testing, and website redesigns that often break conventional scrapers. AI
