We want to compare 3 versions of a web page to extract the nonchanging text (article body content). However the dynamic content on a page is making it a hard problem to solve (ads widgets etc) as dynamic ads give false positives for content changes detected. Therefore, our theory is to visit a page 3 times and we want to exclude all dynamic text that changes on every page refresh. Leaving the article content. In production this will be used on millions of different sites, so footprints can't be used to extract content under a certain tag. It should work for any webpage. It sounds simple, but we need to have a very low memory footprint as it will be done on millions of web pages. The script will return the non-changing text from the html of webpage, and then have a comparison function to compare text difference to other versions of the page to see how much of a change there is. Explain your approach and how it will be faster than any we can think of or if there are any PHP library's you can use to help.

Hello! I'm interested in your project. It seems interesting. I know how to scrape using python (selenium, beautifulsoup and get requests) or Bash (with a more static approach but faster than python) If you're interested tell me more about your job, the ideas you have, the work you've done, etc. Good luck!

Hello, Can you please explain the actual use of the system, I mean why you would like to extract text from millions of websites? This may will help me think of a solution. Now, for low memory footprint we always use core PHP and no library, but then you are scraping millions of sites which means you have to use a library to process the HTML. The best in this case will be XML DOM parser. I think you don't need to visit the website 3 times, this will be 3 times the memory consumption. You need to develop a strong and vast parser. Which can be done using experiences of previous extractions. The whole point is, you cannot built a system in a day, you have to keep it modifying and keep it making better day by day, at least when you are talking about millions of websites. Feel free to contact me anytime. Thanks Meeshal k

Since you need a general scrapper there isn't a very reliable method of doing what you wish to do in all cases especially under the budget requirements. But here are some approaches that might work: Use the block lists of one of the many adblock browser plugins and block resource calls for those servers. Many article based sites have the same basic hierarchical structure. You can compare two or more pages on the same site and see which elements stay unchanged. This can also prevent issues with your current approach where by the site serves ads or "recommended" content based on session data. There are other more sophisticated approaches that can be attempted depending on the time requirements and budget. I work fast and can try different things until the success ratio is to your liking.
