I have an issue with .select which always returns an empty list while practicing webscraping. I am working on the following page: https://presse.ania.net/news/?page=1 using BeautifulSoup.
I am getting and parsing HTML as following:
url = f"https://presse.ania.net/news/?page=1"
headers = {'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.64 Safari/537.36'
mr = requests.get(url, headers = headers)
soupmp = bs(mr.content, "lxml")
I try to retrieve the urls of each articles displayed on the page, under class "title row-space-1" (I use developer tools of chrome to find class, disabled JavaScript like suggested in other posts), and put them in a list called "news"
news = []
for link in soupmp.select("a.title.row-space-1[href]"):
news.append(link.get('href'))
However I keep having an empty list when I print 'news'
[]
Searching on Stackoverflow I tried:
- Disabling JavaScript on website
- Adding a time sleep to let the page download
- Using .find_all, . find and .select, tried with CSS selectors first then kwargs (all return empty list or NoneType object).
None of these worked and I am stuck with my mistake. I think there is something specific in my way of understanding this HTML and selecting class with CSS but I can't find what (partly because I successfully used this code for other websites earlier.).
Could you please educate me on what I am missing?
I appreciate your help!

Try this:
import requests
from bs4 import BeautifulSoup
css = ".card.item.thumbnail.card-topic .title a"
url = f"https://presse.ania.net/news/?page=1"
headers = { 'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.64 Safari/537.36'}
soup = [
f'https://presse.ania.net{a["href"]}' for a in
BeautifulSoup(requests.get(url, headers=headers).content, "lxml").select(css)
]
print("\n".join(soup))

Your css selector is a litte bit wrong way. You can select
.title.row-space-1 > a instead of `a.title.row-space-1[href]`
Scrpt:
from bs4 import BeautifulSoup as bs
import requests
url = "https://presse.ania.net/news/?page=1"

mr = requests.get(url, headers = headers)
print(mr)
soupmp = bs(mr.content, "lxml")
news = []

you could try this and insert the class of the wanted element. I hope that helps you a bit.
soup = BeautifulSoup(html_source, 'html.parser')
# Find element by class which have href attr
el = soup.find(class_='1', href=True)
# Print href value
print(el['href'])
