How to scrape multiple pages using Selenium in Python?

Scraping multiple pages using Selenium in Python generally follows these steps:

  1. Initialize the Selenium web driver.
  2. Navigate to the initial page.
  3. Extract the desired data from the current page.
  4. Check for the presence of the "next page" button/link and navigate to it.
  5. Repeat steps 3-4 until there are no more pages to scrape.
  6. Close the Selenium web driver.

Here's a simple example to illustrate this process:

from selenium import webdriver from selenium.common.exceptions import NoSuchElementException # Initialize the web driver (assumes you have chromedriver in PATH) driver = webdriver.Chrome() # The starting URL (modify as needed) url = "https://example.com/start-page" # List to store scraped data (modify according to your needs) data = [] # Scrape function (modify according to your needs) def scrape_current_page(driver): # Here, extract the data you need, e.g.: items = driver.find_elements_by_class_name("item") for item in items: data.append(item.text) while url: driver.get(url) # Scrape the current page scrape_current_page(driver) try: # Assume the "next" button has a link to the next page next_button = driver.find_element_by_class_name("next") # Check if "next" button is not disabled or if it has a valid URL if next_button.get_attribute("href"): url = next_button.get_attribute("href") else: url = None except NoSuchElementException: # No more "next" button, end the loop url = None # Close the driver driver.close() # Print scraped data (modify as per your requirements) print(data)

Note:

  • Modify the scrape_current_page function and the selector inside the while loop according to the structure of the website you're scraping.
  • Be respectful when scraping websites. Ensure you're not violating the robots.txt file, terms of service, or causing unnecessary load on the server.
  • It's also good practice to incorporate delays (time.sleep(...)) between page requests to avoid overloading the server or getting blocked.
  • Always check the website's robots.txt file before scraping to ensure you have permission to scrape. Some websites might prohibit scraping in their terms of service.
