Day's blog - Yahoo! Pipes Tutorial - An example using the Fetch Page module to make a web scraper

Recently released1 a new Fetch Page module which dramatically increases the number of useful things that Pipes can do. With this new "pipe input" module we're no longer restricted to working with well-organised data sets in supported formats such as CSV, RSS, Atom, XML, JSON, iCal or KML.

Web crawler

For the search engine of the same name, see WebCrawler. Crawlers can validate hyperlinks and HTML code. They can also be used for web scraping (see also data-driven programming). Overview[edit] A Web crawler starts with a list of URLs to visit, called the seeds. The large volume implies that the crawler can only download a limited number of the Web pages within a given time, so it needs to prioritize its downloads. The number of possible URLs crawled being generated by server-side software has also made it difficult for web crawlers to avoid retrieving duplicate content. Crawling policy[edit] The behavior of a Web crawler is the outcome of a combination of policies:[6] a selection policy that states which pages to download,a re-visit policy that states when to check for changes to the pages,a politeness policy that states how to avoid overloading Web sites, anda parallelization policy that states how to coordinate distributed web crawlers.
