BBC Crawler MaxClaw

Description

A powerful, universal web crawler optimized for BBC News but capable of crawling other sites. It integrates advanced scraping technologies including Crawl4AI and Playwright to handle dynamic content and anti-bot protections.

Features

• Multi-Method Extraction:
  • crawl4ai: Primary method using AsyncWebCrawler for high performance and accuracy.
  • playwright: Full browser rendering fallback for complex dynamic pages.
  • requests: Fast fallback for static content.
  • auto: Automatically detects the best method (Prioritizes Crawl4AI).
• Hierarchical Storage: Saves content in a structured format: YYYY-MM-DD/Category/Title.md.
• Local Image Archiving: Downloads images locally, names them by MD5 hash, and updates Markdown references.
• Content Filtering: Intelligently extracts main article content and relevant images using CSS selectors.

Requirements

• Python 3.9+
• See requirements.txt for Python packages.
