python bs4, how to scrape this text in html? - python

the site url:https://n.news.naver.com/mnews/article/421/0006111920
I want to scrape "5" on the below html.
I used this code: soup.select_one('span.u_likeit_text._count').get_text()
the result is '추천'
html code
<span class="u_likeit_text _count num">5</span>

Main issue here that the count is dynamically generated by JavaScript and not present in response and so your soup.
You could use selenium to render the page like a browser will do and convert the driver.page_source to your BeautifulSoup object:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from bs4 import BeautifulSoup
import time
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("https://n.news.naver.com/mnews/article/421/0006111920")
time.sleep(3)
soup = BeautifulSoup(driver.page_source, 'html.parser')
soup.select_one('span.u_likeit_text._count').get_text()
Output:
8

You have to separate the classes using space, instead of connecting over dot.
from bs4 import BeautifulSoup
soup = BeautifulSoup("<span class='u_likeit_text _count num'>5</span>", 'html.parser')
print(soup)
seven_day = soup.find_all("span" , class_="u_likeit_text _count num")
print(seven_day[0].text)

How can I get information from a web site using BeautifulSoup in python?

I have to take the publication date displayed in the following web page with BeautifulSoup in python:
https://worldwide.espacenet.com/patent/search/family/054437790/publication/CN105030410A?q=CN105030410
The point is that when I search in the html code from 'inspect' the web page, I find the publication date fast, but when I search in the html code got with python, I cannot find it, even with the functions find() and find_all().
I tried this code:
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://worldwide.espacenet.com/patent/search/family/054437790/publication/CN105030410A?q=CN105030410')
soup = bs(r.content)
soup.find_all('span', id_= 'biblio-publication-number-content')
but it gives me [], while in the 'inspect' code of the online page, there is this tag.
What am I doing wrong to have the 'inspect' code that is different from the one I get with BeautifulSoup?
How can I solve this issue and get the number?
The problem I believe is due to the content you are looking for being loaded by JavaScript after the initial page is loaded. requests will only show what the initial page content looked like before the DOM was modified by JavaScript.
For this you might try to install selenium and to then download a Selenium web driver for your specific browser. Install the driver in some directory that is in your path and then (here I am using Chrome):
from selenium import webdriver
from selenium.webdriver.common.by import By
from bs4 import BeautifulSoup as bs
options = webdriver.ChromeOptions()
options.add_experimental_option('excludeSwitches', ['enable-logging'])
driver = webdriver.Chrome(options=options)
try:
driver.get('https://worldwide.espacenet.com/patent/search/family/054437790/publication/CN105030410A?q=CN105030410')
# Wait (for up to 10 seconds) for the element we want to appear:
driver.implicitly_wait(10)
elem = driver.find_element(By.ID, 'biblio-publication-number-content')
# Now we can use soup:
soup = bs(driver.page_source, "html.parser")
print(soup.find("span", {"id": "biblio-publication-number-content"}))
finally:
driver.quit()
Prints:
<span id="biblio-publication-number-content"><span class="search">CN105030410</span>A·2015-11-11</span>
Umberto if you are looking for an html element span use the following code:
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://worldwide.espacenet.com/patent/search/family/054437790/publication/CN105030410A?q=CN105030410')
soup = bs(r.content, 'html.parser')
results = soup.find_all('span')
[r for r in results]
if you are looking for an html with the id 'biblio-publication-number-content' use the following code
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://worldwide.espacenet.com/patent/search/family/054437790/publication/CN105030410A?q=CN105030410')
soup = bs(r.content, 'html.parser')
soup.find_all(id='biblio-publication-number-content')
in first case you are fetching all span html elements
in second case you are fetching all elements with an id 'biblio-publication-number-content'
I suggest you look into html tags and elements for deeper understanding on how they work and what are the semantics behind them.

Scraping using beautiful soup not working fully?

I was trying to scrape some data using BeautifulSoup on python from the site 'https://www.geappliances.com/ge-appliances/kitchen/ranges/' which has some products.
import unittest, time, random
from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager
from bs4 import BeautifulSoup
import pandas as pd
links = []
browser = webdriver.Firefox(executable_path="C:\\Users\\drivers\\geckodriver\\win64\\v0.29.1\\geckodriver.exe")
browser.get("https://www.geappliances.com/ge-appliances/kitchen/ranges/")
content = browser.page_source
soup = BeautifulSoup(content, "html.parser")
for main in soup.findAll('li', attrs = {'class' : 'product'}):
name=main.find('a', href=True)
if (name != ''):
links.append((name.get('href')).strip())
print("Got links : ", len(links))
exit()
Here in output I get:-
Got links: 0
I printed the soup and saw that this part was not there in the soup. I have been trying to get around this problem to no avail.
Am I doing something wrong? Any suggestion are appreciated. Thanks.
Study the source of the webpage.Check your findAll function.
You should wait till the page loads. Use time.sleep() to pause execution for a while.
You can try like this.
from bs4 import BeautifulSoup
from selenium import webdriver
import time
url = 'https://www.geappliances.com/ge-appliances/kitchen/ranges/'
driver = webdriver.Chrome("chromedriver.exe")
driver.get(url)
time.sleep(5)
soup = BeautifulSoup(driver.page_source, 'lxml')
u = soup.find('ul', class_='productGrid')
for item in u.find_all('li', class_='product'):
print(item.find('a')['href'])
driver.close()

Parsing data scraped from Javascript rendered webpage with python

I am trying to use .find off of a soup variable but when I go to the webpage and try to find the right class it returns none.
from bs4 import *
import time
import pandas as pd
import pickle
import html5lib
from requests_html import HTMLSession
s = HTMLSession()
url = "https://cryptoli.st/lists/fixed-supply"
def get_data(url):
r = s.get(url)
global soup
soup = BeautifulSoup(r.text, 'html.parser')
return soup
def get_next_page(soup):
page = soup.find('div', {'class': 'dataTables_paginate paging_simple_numbers'})
return page
get_data(url)
print(get_next_page(soup))
The "page" variable returns "None" even though I pulled it from the website element inspector. I suspect it has something to do with the fact that the website is rendered with javascript but can't figure out why. If I take away the {'class' : ''datatables_paginate paging_simple_numbers'} and just try to find 'div' then it works and returns the first div tag so I don't know what else to do.
So you want to scrape dynamic page content , You can use beautiful soup with selenium webdriver. This answer is based on explanation here https://www.geeksforgeeks.org/scrape-content-from-dynamic-websites/
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
url = "https://cryptoli.st/lists/fixed-supply"
driver = webdriver.Chrome('./chromedriver')
driver.get(url)
# this is just to ensure that the page is loaded
time.sleep(5)
html = driver.page_source
# this renders the JS code and stores all
# of the information in static HTML code.
# Now, we could simply apply bs4 to html variable
soup = BeautifulSoup(html, "html.parser")

Python, BS and Selenium

I try to webscrape with javascript dynamic + bs + python and Ive read a lot of things to come up with this code where I try to scrape a price rendered with javascript on a famous website for example:
from bs4 import BeautifulSoup
from selenium import webdriver
url = "https://www.nespresso.com/fr/fr/order/capsules/original/"
browser = webdriver.PhantomJS(executable_path = "C:/phantomjs-2.1.1-windows/bin/phantomjs.exe")
browser.get(url)
html = browser.page_source
soup = BeautifulSoup(html, 'lxml')
soup.find("span", {'class':'ProductListElement__price'}).text
But I only have as a result '\xa0' which is the source value, not the javascript value and I don't know really what I did wrong ...
Best regards
You don't need the expense of a browser. The info is in a script tag so you can regex that out and handle with json library
import requests, re, json
r = requests.get('https://www.nespresso.com/fr/fr/order/capsules/original/')
p = re.compile(r'window\.ui\.push\((.*ProductList.*)\)')
data = json.loads(p.findall(r.text)[0])
products = {product['name']:product['price'] for product in data['configuration']['eCommerceData']['products']}
print(products)
Regex:
Here are two ways to get the prices
from bs4 import BeautifulSoup
from selenium import webdriver
url = "https://www.nespresso.com/fr/fr/order/capsules/original/"
browser = webdriver.Chrome()
browser.get(url)
html = browser.page_source
# Getting the prices using bs4
soup = BeautifulSoup(html, 'lxml')
prices = soup.select('.ProductListElement__price')
print([p.text for p in prices])
# Getting the prices using selenium
prices =browser.find_elements_by_class_name("ProductListElement__price")
print([p.text for p in prices])

Python BeautifulSoup soup.find

I want to scrape some specific data from a website using urllib and BeautifulSoup.
Im trying to fetch the text "190.0 kg". I have tried as you can see in my code to use attrs={'class': 'col-md-7'}
but this returns the wrong result. Is there any way to specify that I want it to return the text between <h3>?
from urllib.request import urlopen
from bs4 import BeautifulSoup
# specify the url
quote_page = 'https://styrkeloft.no/live.styrkeloft.no/v2/?test-stevne'
# query the website and return the html to the variable 'page'
page = urlopen(quote_page)
# parse the html using beautiful soup
soup = BeautifulSoup(page, 'html.parser')
# take out the <div> of name and get its value
Weight_box = soup.find('div', attrs={'class': 'col-md-7'})
name = name_box.text.strip()
print (name)
Since this content is dynamically generated there is no way to access that data using the requests module.
You can use selenium webdriver to accomplish this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from bs4 import BeautifulSoup
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_driver = "path_to_chromedriver"
driver = webdriver.Chrome(chrome_options=chrome_options,executable_path=chrome_driver)
driver.get('https://styrkeloft.no/live.styrkeloft.no/v2/?test-stevne')
html = driver.page_source
soup = BeautifulSoup(html, "lxml")
current_lifter = soup.find("div", {"id":"current_lifter"})
value = current_lifter.find_all("div", {'class':'row'})[2].find_all("h3")[0].text
driver.quit()
print(value)
Just be sure to have the chromedriver executable in your machine.
