I am new to the programming world and have just finished understanding the very basics of Python. I have just started practicing web crawling and have faced a problem already. I have written a very simple code using BeautifulSoup.
from bs4 import BeautifulSoup
from urllib.request import urlopen
response = urlopen('https://trends.google.com/trends/?geo=US/')
soup = BeautifulSoup(response, 'html.parser')
for anchor in soup.select(".list-item-title"):
print(anchor)
I want to retrieve the names of the recently trending stories; however, the code above is not functioning as it's supposed to and returns a blank.
I would be grateful if someone could point out the error. Thank you!
Google Trends(url) is dynamic meaning data is generated by JavaScript and BeautifulSoup can't render javaSceipt.So, You need automation tool something like selenium with BeautifulSoup`. Please just run the code.
Scripts:
from bs4 import BeautifulSoup
import time
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
url = 'https://trends.google.com/trends/?geo=US/'
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.maximize_window()
time.sleep(8)
driver.get(url)
time.sleep(10)
soup = BeautifulSoup(driver.page_source, 'html.parser')
#driver.close()
for anchor in soup.select(".list-item-title"):
print(anchor.text)
Output:
Meta
Lupus
Liga Europy
Chelsea
Prova do lider
Masks in Kenya
UANL

I am in my first attempt in scraping react-based dynamic website - Booking.com search result page. I want to collect the current price of specific hotels under the same conditions.
This site was easy to scrape data with simple CSS selector before, but now they changed how to code and every elements what I want is described with "data-testid" attribute and the series of unknown random numbers, as far as I see in Chrome dev tool. Now the code what I wrote before does not work and I need to rewrite.
Yesterday, I got a wisdom from another question that in this case what I see in Chrome developer tool is different from the HTML contents as of Soup object. So I tried printing the whole soup object beforehand to check the actual CSS, then select elements using these CSS class. I also made sure to use selenium to capture js-illustrated date.
At first this looking good, however, the returned soup object was totally different from what I see. For instance, the request URL should return a hotel called "cup of tea ensemble" on the top of the list with the price for 4 adults for 1 night from 2022-12-22 as its specified in the url params, but when looking into the soup object, the hotel does not come in first and most of the parameters I added in the url are ignored.
Does this usually happen when trying to scrape React-based website? If so, how can I avoid this to collect data as what I see in web browser?
I am not sure if this help but I am attaching the current code what I use. Thank you for reading and I appreciate any advice!

I'm trying to practice some web scraping for a school project, but can't figure out why my script isn't pulling all the listings for a particular region? Would appreciate any help! I've been trying to figure out for hours!
(For simplicity, I'm just sharing one small sub-section of a page i'm trying to scrape. i'm hoping once I can figure out what's wrong here, I can apply it to other regions)
(You might need to create an account to login to see prices, before scraping)
from bs4 import BeautifulSoup
import pandas as pd
import numpy as np
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get('https://condos.ca')
def get_page(page):
url= f'https://condos.ca/toronto/condos-for-sale size_range=300%2C999999999&property_type=Condo%20Apt%2CComm%20Element%20Condo%2CLeasehold%20Condo&mode=Sold&end_date_unix=exact%2C2011&sublocality_id=22&page={page}'
driver.get(url)
page_source = driver.page_source
soup = BeautifulSoup(page_source, 'lxml')
return soup
prices=[]
location=[]
for page in range(5):
soup = get_page(page)
for tag in soup.find_all('div',class_ = 'styles___AskingPrice-sc-54qk44-4 styles___ClosePrice-sc-54qk44-5 dHPUdq hwkkXU'):
prices.append(tag.get_text())
for tag in soup.find_all('address',class_ = 'styles___Address-sc-54qk44-13 gTwVlm'):
location.append(tag.get_text())
For some reason, i'm only getting an output with 48 records, when it should be around 146.
Thanks!
Python Beatifulsoup requests

I am beginner to python. I can't scrape a website where url doesn't change on its next page when load more using requests and beautifulsoup please can someone visit the site let me know the procedure for scraping above websites using beautifulsoup and requests. Any answer would be appreciated Thankyou
Please look this link

You can use selenium in headless mode instead of requests. Eventho selenium is used for web automation it can help you in this case.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
begin = time.time()
options = Options()
options.headless = True
options.add_argument('--log-level=3')
driver = webdriver.Chrome(options=options)
Since the URL doesn't change you have to click on the button that you want by getting its xpath and:
driver.find_element_by_xpath('xpath code').click()
You can avoid using requests and you can get the source code of the page by using:
html_text = driver.page_source
soup = BeautifulSoup(html_text, 'lxml')
I am using selenium for both automation and scraping. Now I found that it's too slow on some of the sites. If i use beautifulSoup then I can scrape them faster but the automation can't be done.
Is there anyway where I can automate the website (button click events etc.) and can also scrape websites with it on beautifulSoup?
Can you give me an example of button/search automation with bs4 + selenium?
Any help would be appreciated...
Example
from bs4 import BeautifulSoup as Soup
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://stackoverflow.com/questions/tagged/beautifulsoup+selenium")
page = Soup(driver.page_source, features='html.parser')
questions = page.select("#questions h3 a[href]")
for question in questions:
print(question.text.strip())
Or Just
import requests
from bs4 import BeautifulSoup as Soup
url = 'https://stackoverflow.com/questions/tagged/beautifulsoup+selenium'
response = requests.get(url=url)
page = Soup(response.text, features='html.parser')
questions = page.select("#questions h3 a[href]")
for question in questions:
print(question.text.strip())
Remember to read https://stackoverflow.com/robots.txt
Absolutely . you can do all the rendering using selenium and pass on the page source to beautifulsoup as follows :
from bs4 import BeautifulSoup as bs
soup = bs(driver.page_source,'html.parser')
This how-to make it live DOM and loaded js so, Enjoy and Save your time searching, the idea is to get the whole body, if you want also head do replace the body, It will be exactly as selenium get, I hope you like it all.
options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
dri = webdriver.Chrome(options=options)
html = dri.find_element_by_tag_name("body").get_attribute('innerHTML')
soup = BeautifulSoup(html, features="lxml")
I am having a problem with bs4 only finding some things in html. To be specific when I try to print span.nav2__menu-link-main-text it selects it and prints it without a problem but when I try to select other part of the page it probably selects it but It doesnt want to print it out. Here is the code that prints and the code that doesnt print:
Tried using different parsers other than lxml and none worked.
#This one prints
from bs4 import BeautifulSoup
import requests
import lxml
url = 'https://osu.ppy.sh/users/18723891'
res = requests.get(url)
soup = BeautifulSoup(res.text, 'lxml')
for i in soup.select('span.nav2__menu-link-main-text'):
print(i.text)
#This one does not print
from bs4 import BeautifulSoup
import requests
import lxml
url = 'https://osu.ppy.sh/users/https://osu.ppy.sh/users/18723891'
res = requests.get(url)
soup = BeautifulSoup(res.text, 'lxml')
for i in soup.select('div.value-dispaly__value'):
print(i.text)
I expect this program to print the current value of div.value-dispaly__value
but when I start the program it prints nothing even tough I can see the value is 4000 when I inspect the page.
It seems that code you are willing to get is dynamically added to the web page by javascript.
In order to update web js part, you have to use requests render() function.
Website page is javascript request rendering to get data, so you need to use automation library like selenium. download selenium web driver as per your browser requirement.
Download selenium web driver for chrome browser:
http://chromedriver.chromium.org/downloads
Install web driver for chrome browser:
https://christopher.su/2015/selenium-chromedriver-ubuntu/
Selenium tutorial:
https://selenium-python.readthedocs.io/
Replace your code to this:
from selenium import webdriver
from bs4 import BeautifulSoup
import time
driver = webdriver.Chrome('/usr/bin/chromedriver')
driver.get('https://osu.ppy.sh/users/12008062')
time.sleep(3)
soup = BeautifulSoup(driver.page_source, 'lxml')
for i in soup.find_all('div',{"class":"value-display__value"}):
print(i.get_text())
