Solving the BS4 Pagination Problem: Extracting All 200 Links Instead of 10

When working with web scraping using Python libraries like BeautifulSoup, one common issue developers encounter is the limitation of results during pagination. In the specific case we are discussing, a user reported that their script was only returning 10 links on the last page of a search instead of the expected 200 links across multiple pages. This guide will walk you through the steps needed to resolve this issue and successfully extract all the links you need.

Understanding the Pagination Problem

The problem arises when attempting to scrape multiple pages of search results. If your script is only fetching the links from the last page, it's crucial to revisit the pagination logic to ensure that all pages are considered. This is a common pitfall due to incorrect parameters or logic in the pagination loop.

Step-by-Step Solution

Here’s a structured breakdown of how to properly implement pagination using BeautifulSoup with a focus on extracting all desired links.

Step 1: Import Required Libraries

Before diving into the code, make sure you have the necessary libraries installed. You will need:

requests: for making HTTP requests

BeautifulSoup: for parsing HTML

Step 2: Define Search Parameters

Define a dictionary to hold the parameters you want to use in your search. In this case, we will include a query for “North Korea”.

Step 3: Create the Main Function

The main function will handle the pagination and gather all the links across those pages. Here's how to structure it:

Step 4: Execute the Main Function

Now you can call the main function by passing the base URL for your search:

Conclusion

By applying this structured approach to handle pagination with BeautifulSoup, you've ensured that your script extracts all 200 links you need instead of just 10 on the last page. This method not only enhances the performance of your scraping tasks but also provides a solid foundation for handling similar issues in future projects.

Happy scraping!
