How to download data from a series of pages?
Example:
- I want to download all data from https://www.example.com/api.php?id=X (fictitious URL), where X is 1 to 1000 and each page is a JSON containing data of a data row. (I don't want to manually add 1000 URLs and OpenRefine seems not allowing pasting list of URLs).
- I want to download information in pages in
https://en.wikipedia.org/wiki/Category:Lists_of_horror_films_by_year, each of which contains one HTML table. - I want to download data in all tables from all pages in https://en.wikipedia.org/wiki/Template:Earthquakes_by_year, each of which contains multiple HTML tables.
