How impossible is this task that's been assigned to my coworkers and I?
Hi, I have read few comments under the post, there are great suggestions also your questions regarding task are on the point. But i believe handling this with a script might be not easy. If i were you, I would use Apache Nutch or similar open source software/library.I have used Nutch for my thesis for similar task that i had to scrap a lot of blog pages and the other pages they were referencing. You can configure all the points in your questions. Like How deep you want to scrap, what kind of content you want to extract? Or there are places, you can extend or modify the behavior, so you can implement your custom logic to parse the html. https://nutch.apache.org
