Open Source Web Scrapers

Web data extraction (web data mining, web scraping) tool. It leverages well proved XML and text processing techologies in order to easely extract useful data from arbitrary web pages.

Supports strings, arrays, arrays of objects, and nested object structures. The schema is not tied to the structure of the page you're scraping, allowing you to pull the data in the structure of your choosing. The API is entirely composable, giving you great flexibility in how you scrape each page. Paginate through websites, scraping each page. X-ray also supports a request delay and a pagination limit. Scraped pages can be streamed to a file, so if there's an error on one page, you won't lose what you've already scraped. Start on one page and move to the next easily. The flow is predictable, following a breadth-first crawl through each of the pages. X-ray has support for concurrency, throttles, delays, timeouts and limits to help you scrape any page responsibly. Swap in different scrapers depending on your needs. Currently supports HTTP and PhantomJS driver drivers. In the future, I'd like to see a Tor driver for requesting pages through the Tor network.
