Use Ruby to scrape prices from Allegro Poland product pages
Allegro is the largest online marketplace in Poland, hosting millions of products from various sellers. Scraping prices from Allegro product pages can be accomplished using Ruby with the Nokogiri gem, which allows efficient parsing and extraction of HTML content. Prices on Allegro are usually prominently displayed near the product title or in a dedicated pricing section, often marked with clear tags and classes that indicate currency and discounts.
The first step is to inspect the Allegro product page using browser developer tools to identify the tags and classes that contain the pricing information. This analysis helps pinpoint the exact structure needed for data extraction. Using Ruby and Nokogiri, the script fetches the product page, parses the HTML, and targets the relevant tags to extract the price. Below is a complete implementation for scraping prices from Allegro Poland product pages:require 'nokogiri' require 'open-uri' # URL of the Allegro product page url = 'https://allegro.pl/oferta/product-page' # Fetch the page content doc = Nokogiri::HTML(URI.open(url)) # Scrape price price_element = doc.at_css('.price') if price_element price = price_element.text.strip puts "Price: #{price}" else puts "Price not found." end -

The script could include a fallback mechanism for when the price element is not found. Adding a log message or saving such cases to a file would help track pages with missing or changed HTML structures.

An improvement would be to scrape additional pricing details, such as discounts or promotional offers, if available. By targeting elements related to sales, the script could provide a more comprehensive pricing analysis.

Saving the scraped prices to a database or structured file, like CSV or JSON, would improve data organization and make it easier to analyze trends. This would also allow for integration with other tools or applications.

To avoid detection by Allegro’s anti-scraping measures, the script could be enhanced with proxy support and user-agent rotation. This would reduce the chances of being blocked while scraping multiple product pages.
