BeautifulSoup Scraping Results not showing

Question

I am playing around with BeautifulSoup to scrape data from websites. So I decided to scrape empireonline’s website for 100 greatest movies of all time.

Here’s the link to the webpage:
https://www.empireonline.com/movies/features/best-movies-2/

I imported the HTML from the site quite alright, I was able to use beautiful soup on it. But when I wanted to get the list of the 100 movie titles, I was getting an empty list.
Here’s the code I wrote below.

import requests
from bs4 import BeautifulSoup

URL = "https://www.empireonline.com/movies/features/best-movies-2/"

response = requests.get(URL)
top100_webpage = response.text

soup = BeautifulSoup(top100_webpage, "html.parser")
movies = soup.find_all(name="h3", class_="jsx-4245974604")
print(movies)

When I ran the code, the result was an empty list. I changed my parsing library to lxml and html5lib but I was still getting the same empty list.

Please how can I resolve this issue?

Answer 1

Might be the fact that the html element ypu are searching for isnt a string . And it’s easier to pass the html file in lxml file instead but that requires installing lxml . Tell me if it worked i am kinda new to coding as well but i thought this might help you

It’s because in this page, the html tags you are looking for (the movie titles) are not in the original html page you request, but are added later by javascript. You can confirm this by loading the page in Chrome with js turned off, you will see the page without film titles.

An alternative for this specific page could be to get the movie titles out of the review links, since the review links all seem to end with the movie title.

BTW the SO question mentioned by @hedgehog in the question comment addresses the exact same problem. In the answers to that another solution is given by using Selenium to actually run javascript to generate the page as we see it in the browser.

The data you need renders dynamically, however, it’s stored as inline JSON. Therefore, we can extract data from there via regular expression. To do that, must look at the page code (Ctrl+U) to find the matches we need and if there are any, try to get them using regular expressions.

This screenshot shows how the page code looks like and the data we need in it:

Since there are a lot of matches, we need to use a regular expressions to find the part of the code we need where the list itself will be directly:

#https://regex101.com/r/CqzweN/1
portion_of_script = re.findall(""Author:42821":{(.*)"Article:54591":", str(all_script))

And then we retrieve the list of movies directly:

#https://regex101.com/r/jRgmKA/1
movie_list = re.findall(""titleText":"(.*?)"", str(portion_of_script))

However, we can extract data by converting parsed inline JSON to usable json using json.loads(<variable_that_stores_json_data>) and then access it as we would access a regular dict.

Do not forget that most sites do not like being scraped and the request might be blocked (if using requests as default user-agent in requests library is a python-requests. Additional step could be to rotate user-agent, for example, to switch between PC, mobile, and tablet, as well as between browsers e.g. Chrome, Firefox, Safari, Edge and so on.

You can check the fully working code in online IDE.

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

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36",
}

html = requests.get("https://www.empireonline.com/movies/features/best-movies-2/", headers=headers, timeout=30)
soup = BeautifulSoup(html.text, "lxml")
all_script = soup.select("script")

#https://regex101.com/r/CqzweN/1
portion_of_script = re.findall(""Author:42821":{(.*)"Article:54591":", str(all_script)) 

#https://regex101.com/r/jRgmKA/1
movie_list = re.findall(""titleText":"(.*?)"", str(portion_of_script))    

print(json.dumps(movie_list, indent=2, ensure_ascii=False))
