Scraping the necessary information once on the website,
I want to scrape only the updated information in a few days.
For example, information posted on the following bulletin board site
If there is little information posted, you can turn the same program again to update the entire information,
A large amount of information is inefficient because it takes a lot of time.
I would be happy if you could tell me about the methodology.
It can be a helpful resource, so thanks for your cooperation.
Answer # 1
I don't look at the site, but if the article is added on the bulletin board and the past is not corrected, only the last acquisition time and the number after the last acquisition number I think I should take it.
is too obvious and may not be the answer you expect. In that case, please write what you expect.
