Soup does not find specific class from div

I have tried everything. The response is perfect and I do get what I am supposed to be getting, I just don't understand why I receive an empty array when I'm searching for a div with a specific class (that definitely exists) on the web page. I have tried looking everywhere, but nothing seems to work.

Here's my code:

import requests
import lxml
from bs4 import BeautifulSoup

baseurl = 'https://www.atea.dk/eshop/products/?filters=S_Apple%20MacBook%20Pro%2016%20GB'

response = requests.get(baseurl)
soup = BeautifulSoup(response.content, 'lxml')

productlist = soup.find_all("div", class_="nsv-product ns_b_a")

print(productlist)

I am essentially trying to build a script that emails me when the items from an e-shop are marked as available (pa lager) instead of unavailable (ikke pa lager).

You might need to use Selenium on this one.

The div is, AFAIK, rendered by JS.

BeautifulSoup does not capture JS-rendered content.

from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager
from selenium.webdriver.common.keys import Keys
options = webdriver.FirefoxOptions()
options.headless = True
driver = webdriver.Firefox(executable_path=GeckoDriverManager().install(),options=options)
driver.get('https://www.atea.dk/eshop/products/?filters=S_Apple%20MacBook%20Pro%2016%20GB')
k = driver.find_elements_by_xpath("//div[@class='nsv-product ns_b_a']")

Your code below that snippet should contains everything you need, e.g. processing, saving into your database, etc..

Note: That snippet is a bit flawed, e.g. you want to use Chrome, but it only provides an example, so tweak it to your own needs.

You need to inspect the page source code (for windows : Ctrl + U) and search for this section window.netset.model.productListDataModel

it's enclosed in <script> tag.

What you need to do is to parse that enclosed json string <script>window.netset.model.productListDataModel = {....}
which will provide your desired product listing (8 per page).

Here is the code

import re, json
import requests
import lxml
from bs4 import BeautifulSoup

baseurl = 'https://www.atea.dk/eshop/products/?filters=S_Apple%20MacBook%20Pro%2016%20GB'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36'}
response = requests.get(baseurl, headers=headers)
soup = BeautifulSoup(response.content, 'lxml')

# print response
print(response)

# regex to find the script enclosed json string
product_list_raw_str = re.findall(r'productListDataModel\s+=\s+(\{.*?\});\n', response.text)[0].strip()

# parse json string
products_json = json.loads(product_list_raw_str)

# find the product list
product_list = products_json['response']['productlistrows']['productrows']

# check product list count, 8 per page
len(product_list)

# iterate the product list
for product in product_list:
  print(product)

It will output -

<Response [200]>
{'buyable': True, 'ispackage': False, 'artcolumndata': 'MK1E3DK/A', 'quantityDisabled': False, 'rowid': '5418526',.........
..... 'showAddToMyList': False, 'showAddToCompareList': True, 'showbuybutton': True}
