Extracting and Organizing Content from Older Websites: A Solution for Structured Documentation Including Mouse-Over Images

Short summary

Technical guide for extracting structured data from legacy websites with dynamically-loaded elements. Compares three approaches (network inspection, browser automation with Selenium/Puppeteer, DOM manipulation) with mechanisms, trade-offs, and failure-mode solutions. Practical for developers maintaining data pipelines from outdated systems.

• •Three extraction strategies: network request inspection (fastest), browser automation (most reliable), DOM manipulation (most precise)
• •Fixed-width layouts and AJAX-loaded content break standard scraping; requires matching tool to site architecture
• •Common failure modes: incomplete hover triggering, dynamic content timing, legal risks from aggressive scraping
