Use Go to scrape product categories from Media Markt Poland
Media Markt is a leading retailer in Poland, specializing in electronics and appliances. Scraping product categories from Media Markt involves navigating the main website or specific category pages to extract hierarchical information about their product offerings. Categories are typically structured in a menu or sidebar, and they are often presented as clickable links leading to subcategories or product pages. Using Go and the Colly library, this task can be accomplished efficiently by targeting these specific elements.
The process begins by inspecting the website’s HTML structure using browser developer tools to locate the relevant tags and attributes for the categories. Using Colly, the script crawls the page, identifies the category sections, and extracts their text and URLs for further navigation. Below is a complete Go implementation for scraping product categories from Media Markt Poland:package main import ( "fmt" "log" "github.com/gocolly/colly" ) func main() { // Create a new Colly collector c := colly.NewCollector() // Handle the scraping of category names and links c.OnHTML(".category-menu-item", func(e *colly.HTMLElement) { categoryName := e.Text categoryURL := e.Attr("href") fmt.Printf("Category: %s\nLink: %s\n", categoryName, categoryURL) }) // Handle errors during scraping c.OnError(func(_ *colly.Response, err error) { log.Printf("Error: %v\n", err) }) // Visit the Media Markt Poland homepage err := c.Visit("https://mediamarkt.pl/") if err != nil { log.Fatalf("Failed to visit website: %v", err) } } -

The script could be improved by implementing recursive scraping for subcategories. After collecting the main categories, the script can follow their links to extract subcategories and build a complete hierarchy.

Adding error handling for missing or malformed category links would make the script more robust. For example, logging any categories without valid URLs ensures that incomplete data can be reviewed and addressed.

To handle anti-scraping measures, adding user-agent rotation and proxy support would make the script more resilient. This would allow for consistent access to Media Markt’s website while minimizing the risk of being blocked.
