Answer a question

This page contains a list of all of the games available on Xbox Game Pass. I'd like to use BeautifulSoup to retrieve a list of the game names.

This is what I'm doing:

import requests
from bs4 import BeautifulSoup

page = requests.get('https://www.xbox.com/en-US/xbox-game-pass/games?=pcgames')

if (page.status_code != 200):
    print("Unable to load game pass games page")
    exit()

soup = BeautifulSoup(page.content, 'html.parser')
soup.find_all('h3', class_='gameDevLink') # returns []

s = soup.prettify()

with open('dump.html', 'w', encoding='utf-8') as f:
    f.write(s)

If I inspect a game on the page I see something like this:

Inspecting a game's html

Each game is enclosed in an 'a' tag with its class set to gameDevLink.

My problem is that soup.find_all('a', class_='gameDevLink') returns no hits.

If I save the html generated by BeautifulSoup to disk and search for gameDevLink there are, again, no hits.

I don't understand why I can see the information in my browser but BeautifulSoup doesn't seem to see it.

The info about games is loaded from other URL via Javascript. You can use this script to simulate it:

import json
import requests
from bs4 import BeautifulSoup


headers = {'User-Agent': 'User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36'}
game_ids_url = 'https://catalog.gamepass.com/sigls/v2?id=fdd9e2a7-0fee-49f6-ad69-4354098401ff&language=en-us&market=US'
game_info_url = 'https://displaycatalog.mp.microsoft.com/v7.0/products?bigIds={}&market=US&languages=en-us&MS-CV=XXX'

game_ids = requests.get(game_ids_url).json()
s = ','.join(i['id'] for i in game_ids if 'id' in i)
    
data = requests.get(game_info_url.format(s)).json()

# uncomment this to print all data:
#print(json.dumps(data, indent=4))

# print some data to screen:
for p in data['Products']:
    print(p['LocalizedProperties'][0]['ProductTitle'])
    print(p['LocalizedProperties'][0]['ShortDescription'])
    print('-' * 80)
