Replacing Fragile CSS Selectors with LLM-Powered Zero-Shot JSON Extraction
Large Language Models are being used to replace fragile CSS selectors in web scraping, offering a more robust method for data extraction. This zero-shot JSON extraction approach allows LLMs to semantically map unstructured web content to predefined schemas, making scraping pipelines resilient to website changes. By cleaning and converting HTML to Markdown before feeding it to an LLM, the process reduces token consumption, latency, and improves accuracy by mitigating the "lost in the middle" problem. AI
