How can I scrape items off a site from the last five days?
—Scrapy User
That question started the development of scrapy-mosquitera, a tool to help you restrict crawling and scraping scope using matchers.
Matchers are simple Python functions that return the validity of an element under certain restrictions.
The first goal in the project was date matching, but you can create your own matcher for your own crawling and scraping needs.
How it works
In the case where the dates are available in the URLs, you will just use the matcher function directly in your code:
from scrapy_mosquitera.matchers import date_matches
date = scrape_date_from_url(url)
if date_matches(data=date, after='5 days ago'):
yield Request(url=url, callback=self.parse_item)
To handle the case when the date is only available at the time when you scrape the items, scrapy-mosquitera provides a PaginationMixin to control the crawl according to the dates scraped.
Head on to the remaining of the documentation for more details.
