I was trying to scrape some url's from a particular link, I used beautiful-soup for scraping those links, but I'm not able to scrape those links. Here I'm attaching the code which I have used. Actually, I want to scrape the urls from the class "fxs_aheadline_tiny"
import requests
from bs4 import BeautifulSoup
url = 'https://www.fxstreet.com/news?q=&hPP=17&idx=FxsIndexPro&p=0&dFR%5BTags%5D%5B0%5D=EURUSD'
r1 = requests.get(url)
coverpage = r1.content
soup1 = BeautifulSoup(coverpage, 'html.parser')
coverpage_news = soup1.find_all('h4', class_='fxs_aheadline_tiny')
print(coverpage_news)
Thank you
I would use Selenium.
Please, try this code:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.options import Options
#open driver
driver= webdriver.Chrome(ChromeDriverManager().install())
driver.get('https://www.fxstreet.com/news?q=&hPP=17&idx=FxsIndexPro&p=0&dFR%5BTags%5D%5B0%5D=EURUSD')
# Use ChroPath to identify the xpath for the 'page hits'
pagehits=driver.find_element_by_xpath("//div[#class='ais-hits']")
# search for all a tags
links=pagehits.find_elements_by_tag_name("a")
# For each link get the href
for link in links:
print(link.get_attribute('href'))
It exactly does what you want: it takes out all urls/links on your search page (that means also the links to the authors pages).
You could even consider automating the browser and moving through the search page results. See for this the Selenium documentation:https://selenium-python.readthedocs.io/
Hope this helps

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.
I am looking to scrape the following web page, where I wish to scrape all the text on the page, including all the clickable elements.
I've attempted to use requests:
import requests
response = requests.get("https://cronoschimp.club/market/details/2424?isHonorary=false")
response.text
Which scrapes the meta-data but none of the actual data.
Is there a way to click through and get the elements in the floating boxes?
As it's a Javascript enabled web page, you can't get anything as output using requests, bs4 because they can't render javascript. So, you need an automation tool something like selenium. Here I use selenium with bs4 and it's working fine. Please, see the minimal working example as follows:
Code:
from bs4 import BeautifulSoup
import time
from selenium import webdriver
driver = webdriver.Chrome('chromedriver.exe')
driver.maximize_window()
time.sleep(8)
url = 'https://cronoschimp.club/market/details/2424?isHonorary=false'
driver.get(url)
time.sleep(20)
soup = BeautifulSoup(driver.page_source, 'lxml')
name = soup.find('div',class_="DetailsHeader_title__1NbGC").get_text(strip=True)
p= soup.find('span',class_="DetailsHeader_value__1wPm8")
price= p.get_text(strip=True) if p else "Not for sale"
print([name,price])
Output:
['Chimp #2424', 'Not for sale']
I am trying to webscrape form the website https://roll20.net/compendium/dnd5e/Monsters%20List#content and having some issues.
My first script I tried kept returning an empty list when finding by div and class name, which I believe is do to the site using Javascript? But a little uncertain if that is the case or not.
Here was my first attempt:
import requests
from bs4 import BeautifulSoup
import pandas as pd
page = requests.get('https://roll20.net/compendium/dnd5e/Monsters%20List#content')
soup = BeautifulSoup(page.text, 'html.parser')
card = soup.find_all("div", class_='card')
print(card)
This one returns an empty list so then I tired to use Selenium and scrape with that. Here is that script:
import requests
from bs4 import BeautifulSoup
import pandas as pd
from selenium import webdriver
url='https://roll20.net/compendium/dnd5e/Monsters%20List#content'
driver = webdriver.Firefox(executable_path = 'C:\Windows\System32\geckodriver')
driver.get(url)
page = driver.page_source
page_soup = soup(page,'html.parser')
Starting the script with that I then tried all 3 of these different options (individually ran these, just listed them here together for simplicity sake):
for card in body.find('div', {"class":"card"}):
print(card.text)
print(card)
for card in body.find_all('div', {"class":"card"}):
print(card.text)
print(card)
card = body.find_all('div', {"class":"card"})
print(card)
All of them return the same error message:
AttributeError: ResultSet object has no attribute 'find'. You're probably treating a list of elements like a single element. Did you call find_all() when you meant to call find()?
Where am I going wrong here?
Edit:
Fazul thank you for your input on this I guess I should be more specific. I was more looking to get the contents of each card. For example, the card has a "body" class and within that body class there are many fields that is the data I am looking to extract. Maybe I am misunderstanding your script and what you stated. Here is a screen shot to maybe help specify my question a bit more to what content I am looking to extract.
So everything that would be under the body i.e. name, title, subtitle, etc.. Those were the texts I was trying to extract.
That page is being loaded by JavaScript. So beautifulsoup will not work in this case. You have to use Selenium.
And the element that you are looking for - <div> with class name as card show up only when you click on the drop-down arrow. Since you are not doing any click event in your code, you get an empty result.
Use selenium to click the <div> with class name as dropdown-toggle. That click event loads the <div class='card'>
Then you can scrape the data you need.
Since the page is loaded by JavaScript, you have to use Selenium.
My solution As follows:
Every card has a link as shown:
Use BeautifulSoup to get the link for each card, Then open each link using Selenium in headless mode because it is also loaded by JavaScript.
Then you get the data you need for each card using BeautifulSoup
Working code:
from selenium import webdriver
from webdriver_manager import driver
from webdriver_manager.chrome import ChromeDriver, ChromeDriverManager
from selenium.webdriver.chrome.options import Options
from time import sleep
from bs4 import BeautifulSoup
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("https://roll20.net/compendium/dnd5e/Monsters%20List#content")
page = driver.page_source
# Wait until the page is loaded
sleep(13)
soup = BeautifulSoup(page, "html.parser")
# Get all card urls
urls = soup.find_all("div", {"class":"header inapp-hide single-hide"})
cards_list = []
for url in urls:
card = {}
card_url = url.a["href"]
card_link = f'https://roll20.net{card_url}#content'
# Open chrom in headless mode
chrome_options = Options()
chrome_options.add_argument("--headless")
driver = webdriver.Chrome(ChromeDriverManager().install(), options=chrome_options)
driver.get(card_link )
page = driver.page_source
soup = BeautifulSoup(page, "html.parser")
card["name"] = soup.select_one(".name").text.split("\n")[1]
card["subtitle"] = soup.select_one(".subtitle").text
# Do the same to get all card detealis
cards_list.append(card)
driver.quit()
Library you need to install
pip install webdriver_manager
This library open chrome driver without the need to geckodriver and get up to date driver for you.

u can get the json data from this link instead just parse it and get the data you need
Python Beatifulsoup requests
import requests
import re
import os
import csv
from bs4 import BeautifulSoup
for d in searche:
truelink = d.replace(" ","-")
truelinkk=('https://www.fb.com
r = requests.get(truelinkk,headers=headers).text
soup=BeautifulSoup(r,'lxml')
mobile=soup.find_all('li',class_='EIR5N')
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'm trying to scrape all links from https://www.udemy.com/courses/search/?q=sql&src=ukw&lang=en however without even selecting an element, my code retrieves no links. Please see my code below.
import bs4,requests as rq
Link = 'https://www.udemy.com/courses/search/?q=sql&src=ukw&lang=en'
RQOBJ = rq.get(Link)
BS4OBJ = bs4.BeautifulSoup(RQOBJ.text)
print(BS4OBJ)
hope you want link of courses on the page, this code will help
from selenium import webdriver
from bs4 import BeautifulSoup
import time
baseurl='https://www.udemy.com'
url="https://www.udemy.com/courses/search/?q=sql&src=ukw&lang=en"
driver = webdriver.Chrome()
driver.maximize_window()
driver.get(url)
time.sleep(5)
content = driver.page_source.encode('utf-8').strip()
soup = BeautifulSoup(content,"html.parser")
courseLink = soup.findAll("a", {"class": "card__title",'href': True})
for link in courseLink:
print baseurl+link['href']
driver.quit()
It will print:
