Which is better: Python or Ruby for scraping product reviews from eBay?
Scraping product reviews from eBay can be a challenging yet rewarding task. Python and Ruby are both popular choices for web scraping, but which one works better for this purpose? Python is known for its powerful scraping libraries like BeautifulSoup and Scrapy, making it ideal for handling static and dynamic content. Ruby, on the other hand, offers a clean and intuitive syntax with Nokogiri, which is excellent for parsing HTML efficiently. But how do these languages handle eBay’s dynamic loading of reviews? Can Python’s Selenium or Ruby’s Watir handle JavaScript-heavy pages more effectively?
Let’s start with a Python implementation using BeautifulSoup to scrape static reviews. While it works well for non-dynamic content, it might need Selenium for JavaScript-rendered reviews.import requests from bs4 import BeautifulSoup # URL of an eBay product page url = "https://www.ebay.com/product-page" headers = {"User-Agent": "Mozilla/5.0"} response = requests.get(url, headers=headers) if response.status_code == 200: soup = BeautifulSoup(response.content, "html.parser") reviews = soup.find_all("div", class_="review-item") for idx, review in enumerate(reviews, 1): reviewer = review.find("span", class_="reviewer-name").text.strip() if review.find("span", class_="reviewer-name") else "Anonymous" comment = review.find("p", class_="review-text").text.strip() if review.find("p", class_="review-text") else "No comment" print(f"Review {idx}: {reviewer} - {comment}") else: print("Failed to fetch the page. Status code:", response.status_code)Now, let’s consider Ruby, using Nokogiri. Its syntax is straightforward and works well for static HTML:
require 'nokogiri' require 'open-uri' # URL of an eBay product page url = 'https://www.ebay.com/product-page' # Fetch and parse the HTML doc = Nokogiri::HTML(URI.open(url)) # Scrape reviews reviews = doc.css('.review-item') if reviews.any? reviews.each_with_index do |review, index| reviewer = review.at_css('.reviewer-name')&.text&.strip || 'Anonymous' comment = review.at_css('.review-text')&.text&.strip || 'No comment' puts "Review #{index + 1}: #{reviewer} - #{comment}" end else puts "No reviews found." endBoth implementations have their pros and cons. Python provides more flexibility when handling dynamic content, while Ruby offers clean and concise syntax for static content. If you’re dealing with paginated reviews or JavaScript-rendered elements, Python’s Selenium might be a better choice.

Python’s extensive library ecosystem, such as Scrapy and Selenium, makes it more versatile for complex scraping tasks. It is especially useful for handling JavaScript-rendered reviews on dynamic pages.
-
Ruby’s Nokogiri is lightweight and simple to use, making it ideal for beginners or for scraping static HTML. However, it may struggle with dynamic content without additional libraries like Watir.
-
For paginated reviews, both Python and Ruby can be enhanced to iterate through multiple pages. Python’s Scrapy framework, for example, provides built-in support for handling pagination efficiently.
-
When dealing with large-scale scraping, Python’s multiprocessing capabilities give it a performance edge. Ruby, while elegant, might require more manual handling for parallel requests.
-
Dynamic content rendering on eBay could benefit from Python’s Selenium integration. It can simulate browser behavior and ensure all reviews are fully loaded before scraping.
-
Ruby’s community and libraries are great for smaller projects, but Python’s vast resources make it more suitable for scraping tasks that require data analysis or machine learning integration.

To improve reliability, both implementations could include error handling for network issues and missing elements. Logging missing data and retrying failed requests would make the scrapers more robust.
