I guess they have changed the site's html again?

Yes, it looks like there was a small change, the "Page 1 of 3" at the top of the page changed when launched in WebDriver so the scraper could not identify the maximum number of pages. I will be adding a fix today in the number_of_pages line to target the next page arrow element at the bottom of the page instead 😊

Nice!

To work with the latest version of xlsxwriter, I've updated: writer.save() to: writer.close()

In the case where there aren't multiple pages, I've updated this a little: try: pagination_next_element = content.find("a", attrs={"data-testid": "pagination-next"}) if pagination_next_element is not None: number_of_pages = pagination_next_element.get("aria-label")[-1] else: number_of_pages = 1

I've also specified a specific trim with: "&aggregatedTrim={car['trim']}&"

And in the definition of cars, you can just leave the trim as an empty string if you aren't specifying

Also can be handy to have output to Excel is the "subtitle" of the ad: try: subtitle = article.find("p", attrs={"data-testid": "search-listing-subtitle"}).text details["variant"] = subtitle except: print("Subtitle not found.")

Provides details on the variant (e.g. if you're choosing electric, what the kWh of the battery is)

This is great, thank you for your work on this.

I tried the updated code but the max pages is still hampering me - can only scrape a few pages max.

[R2Squared]

this code fixed the problem for me: try: pagination_next_element = content.find("a", attrs={"data-testid": "pagination-next"}) aria_label = pagination_next_element.get("aria-label") number_of_pages = int(re.search(r'of (\d+)', aria_label).group(1)) except AttributeError: print("No results found or couldn't determine number of pages.") continue except Exception as e: print(f"An error occurred while determining number of pages: {e}") continue
