MULTIPLE URL EXTRACTOR CODE
Here is the code to get the clean list of URLs. This makes the first method we saw useless, as with this one, we can get all the same information, and more! The URLs need to come from the same website!įor every hostel page, I scraped the name of the hostel, the cheapest price for a bed, the number of reviews and the review score for the 8 categories (location, atmosphere, security, cleanliness, etc.). It’s important to point out that if every page scraped has a different structure, the method will not work properly.
Clean the data and create a list containing all the URLs collected.Create a “for” loop scraping all the href attributes (and so the URLs) for all the pages we want.We see that every hostel listing has a href attribute, which specifies the link to the individual hostel page. Thankfully, there is a better/smarter way to do things.
MULTIPLE URL EXTRACTOR FREE
That works if you have just a few URLs, but imagine if you have a 100, 1,000 or even 10,000 URLs! Surely, creating a list manually is not what you want to do (unless you got a loooot of free time)! Then, you could create a new “for” loop that goes over every element of the list and collects the information you want, in exactly the same way as shown in the first method. Here is the code to create the list of URLs for the first two hostels: url =
Well, the first way to do this is to manually create a list of URLs, and loop through that list. That’s great, but what if the different URLs you want to scrape don’t have the page number you can loop through? Also, what if I want specific information that is only available on the actual page of the hostel? Loop over a manually created list of URLs
