My problem is that I am attempting to scrape the titles of Netflix movies and shows from a website that lists them on 146 different pages, so I made a loop to try and capture data from all the pages, however, when using the loop it makes my URL malformed and I don't know how to fix it.
I have made sure the webdriver part of the code works, meaning if I type in the URL to the driver.get it gives me the information I need, however when using the loop it pops up multiple firefox windows and doesnt put any URL into any of the windows. I also added a time delay to try and see if it was changing the URL before it got used but it still didn't work.
from selenium import webdriver
import time
for i in range(1,3):
URL = "https://flixable.com/?min-rating=0&min-year=1920&max-year=2019&order=date&page={}"
newURL = URL.format(i)
print(newURL)
time.sleep(10)
driver = webdriver.Firefox()
driver.get('newURL')
titles = driver.find_elements_by_css_selector('#filterContainer > div > div > p > strong > a')
for post in titles:
print(post.text)

I am attempting to web-scrape info off of the following website: https://www.axial.net/forum/companies/united-states-family-offices/
I am trying to scrape the description for each family office, so "https://www.axial.net/forum/companies/united-states-family-offices/"+insert_company_name" are the pages I need to scrape.
So I wrote the following code to test the program for just one page:
from bs4 import BeautifulSoup as soup
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Chrome('insert_path_here/chromedriver')
driver.get("https://network.axial.net/company/ansaco-llp")
page_source = driver.page_source
soup2 = soup(page_source,"html.parser")
soup2.findAll('axl-teaser-description')[0].text
This works for the single page, as long as the description doesn't have a "show full description" drop down button. I will save that for another question.
I wrote the following loop:
#Note: Lst2 has all the names for the companies. I made sure they match the webpage
lst3=[]
for key in lst2[1:]:
driver.get("https://network.axial.net/company/"+key.lower())
page_source = driver.page_source
for handle in driver.window_handles:
driver.switch_to.window(handle)
word_soup = soup(page_source,"html.parser")
if word_soup.findAll('axl-teaser-description') == []:
lst3.append('null')
else:
c = word_soup.findAll('axl-teaser-description')[0].text
lst3.append(c)
print(lst3)
When I run the loop, all of the values come out as "null", even the ones without "click for full description" buttons.
I edited the loop to instead print out "word_soup", and the page is different then if I had run it without a loop and does not have the description text.
I don't understand why a loop would cause that but apparently it does. Does anyone know how to fix this problem?
Found solution. pause the program for 3 seconds after driver.get:
import time
lst3=[]
for key in lst2[1:]:
driver.get("https://network.axial.net/company/"+key.lower())
time.sleep(3)
page_source = driver.page_source
word_soup = soup(page_source,"html.parser")
if word_soup.findAll('axl-teaser-description') == []:
lst3.append('null')
else:
c = word_soup.findAll('axl-teaser-description')[0].text
lst3.append(c)
print(lst3)
I see that the page uses javascript to generate the text meaning it doesn't show up in the page source, which is weird but ok. I don't quite understand why you're only iterating through and switching to all the instances of Selenium you have open, but you definitely won't find the description in the page source / beautifulsoup.
Honestly, I'd personally look for a better website if you can, otherwise, you'll have to try it with selenium which is inefficient and horrible.
I'm practicing web scraping with Python atm and I found a problem, I wanted to scrape one website that has a list of anime that I watched before but when I try to scrape it (via requests or selenium) it only gets around 30 of 110 anime names from the page.
Here is my code with selenium:
from selenium import webdriver
from bs4 import BeautifulSoup
browser = webdriver.Firefox()
browser.get("https://anilist.co/user/Agusmaris/animelist/Completed")
data = BeautifulSoup(browser.page_source, 'lxml')
for title in data.find_all(class_="title"):
print(title.getText())
And when I run it, the page source only shows up until an anime called 'Golden time' when there are like 70 or more left that are in the page.
Thanks
Edit: Code that works now thanks to 'supputuri':
from selenium import webdriver
from bs4 import BeautifulSoup
import time
driver = webdriver.Firefox()
driver.get("https://anilist.co/user/Agusmaris/animelist/Completed")
time.sleep(3)
footer = driver.find_element_by_css_selector("div.footer")
preY = 0
print(str(footer))
while footer.rect['y'] != preY:
preY = footer.rect['y']
footer.location_once_scrolled_into_view
print('loading')
html = driver.page_source
soup = BeautifulSoup(html, 'lxml')
for title in soup.find_all(class_="title"):
print(title.getText())
driver.close()
driver.quit()
ret = input()
Here is the solution.
Make sure to add import time
driver.get("https://anilist.co/user/Agusmaris/animelist/Completed")
time.sleep(3)
footer =driver.find_element_by_css_selector("div.footer")
preY =0
while footer.rect['y']!=preY:
preY = footer.rect['y']
footer.location_once_scrolled_into_view
time.sleep(1)
print(str(driver.page_source))
This will iterate until all the anime is loaded and then gets the page source.
Let us know if this was helpful.
So, this is the jist of what I get when I load the page source:
AniListwindow.al_token = 'E1lPa1kzYco5hbdwT3GAMg3OG0rj47Gy5kF0PUmH';Sorry, AniList requires Javascript.Please enable Javascript or http://outdatedbrowser.com>upgrade to a modern web browser.Sorry, AniList requires a modern browser.Please http://outdatedbrowser.com>upgrade to a newer web browser.
Since I know damn well that Javascript is enabled and my Chrome version is fully up to date, and the URL listed takes one to a nonsecure website to "download" a new version of your browser, I think this is a spam site. Not sure if you were aware of that when posting so I won't flag as such, but I wanted you and others who come across this to be aware.
I want to scrape, e.g., the title of the first 200 questions under the web page https://www.quora.com/topic/Stack-Overflow-4/all_questions. And I tried the following code:
import requests
from bs4 import BeautifulSoup
url = "https://www.quora.com/topic/Stack-Overflow-4/all_questions"
print("url")
print(url)
r = requests.get(url) # HTTP request
print("r")
print(r)
html_doc = r.text # Extracts the html
print("html_doc")
print(html_doc)
soup = BeautifulSoup(html_doc, 'lxml') # Create a BeautifulSoup object
print("soup")
print(soup)
It gave me a text https://pastebin.com/9dSPzAyX. If we search href='/, we can see that the html does contain title of some questions. However, the problem is that the number is not enough; actually on the web page, a user needs to manually scroll down to trigger extra load.
Does anyone know how I could mimic "scrolling down" by the program to load more content of the page?
Infinite scrolls on a webpage is based on the Javascript functionality. Therefore, to find out what URL we need to access and what parameters to use, we need to either thoroughly study the JS code working inside the page or, and preferably, examine the requests that the browser does when you scroll down the page. We can study requests using the Developer Tools.
See example for quora
the more you scroll down, the more requests generated. so now your requests will be done to that url instead of normal url but keep in mind to send correct headers and playload.
other easier solution will be by using selenium
Couldn't find a response using request. But you can use Selenium. First printed out the number of questions at first load, then send the End key to mimic scrolling down. You can see number of questions went from 20 to 40 after sending the End key.
I used driver.implicitly wait for 5 seconds before loading the DOM again in case the script load to fast before the DOM was loaded. You can improve by using EC with selenium.
The page loads 20 questions per scroll. So if you are looking to scrape 100 questions, then you need to send the End key 5 times.
To use the code below you need to install chromedriver.
http://chromedriver.chromium.org/downloads
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
CHROMEDRIVER_PATH = ""
CHROME_PATH = ""
WINDOW_SIZE = "1920,1080"
chrome_options = Options()
# chrome_options.add_argument("--headless")
chrome_options.add_argument("--window-size=%s" % WINDOW_SIZE)
chrome_options.binary_location = CHROME_PATH
prefs = {'profile.managed_default_content_settings.images':2}
chrome_options.add_experimental_option("prefs", prefs)
url = "https://www.quora.com/topic/Stack-Overflow-4/all_questions"
def scrape(url, times):
if not url.startswith('http'):
raise Exception('URLs need to start with "http"')
driver = webdriver.Chrome(
executable_path=CHROMEDRIVER_PATH,
chrome_options=chrome_options
)
driver.get(url)
counter = 1
while counter <= times:
q_list = driver.find_element_by_class_name('TopicAllQuestionsList')
questions = [x for x in q_list.find_elements_by_xpath('//div[#class="pagedlist_item"]')]
q_len = len(questions)
print(q_len)
html = driver.find_element_by_tag_name('html')
html.send_keys(Keys.END)
wait = WebDriverWait(driver, 5)
time.sleep(5)
questions2 = [x for x in q_list.find_elements_by_xpath('//div[#class="pagedlist_item"]')]
print(len(questions2))
counter += 1
driver.close()
if __name__ == '__main__':
scrape(url, 5)
I recommend using selenium rather than bs.
selenium can control browser and parsing. like scroll down, click button, etc…
this example is for scroll down for get all liker user in instagram.

If the content only loads on "scrolling down", this probably means that the page is using Javascript to dynamically load the content.
You can try using a web client such as PhantomJS to load the page and execute the javascript in it, and simulate the scroll by injecting some JS such as document.body.scrollTop = sY; (Simulate scroll event using Javascript).
I have scraped a site for 840 urls...
When I rebuld the urls for more insformation, my python scraper does not porvide the same data as if I manually click on the links.
For example, when I visit this website, https://salesweb.civilview.com/Sales/SalesSearch
If I click on the first 'Details' in the list, it take to a page with more information.
The information that is given is a relative link showing '/Sales/SaleDetails?PropertyId=254119896'
I've scraped the 'details' relative link and then rebuilt the link to match the absolute address.
this address becomes
https://salesweb.civilview.com/Sales/SaleDetails?PropertyId=254119896
However when I do this and try to scrape, I get a total different set of data and it takes me to a general landing page.
https://salesweb.civilview.com/
I thought at first, I needed to use a headless browser to fix the problem, but now I am not sure.
Here is my code:
import time
from selenium import webdriver
baseurl='https://salesweb.civilview.com'
link='/Sales/SaleDetails?PropertyId=254119946'
url1=baseurl+link
driver = webdriver.PhantomJS()
driver.get(url1)
html = driver.page_source
time.sleep(10)
driver.quit()
I found a workaround, if you first interact with the website, you can access the others urls. Unfortunately I have no idea why it works:
driver = webdriver.PhantomJS()
driver.get("https://salesweb.civilview.com/")
driver.find_element_by_link_text('Atlantic County, NJ').click()
driver.get("https://salesweb.civilview.com/Sales/SaleDetails?PropertyId=254119946")
html = driver.page_source
print(html)
I'm fairly new to coding and Python so I apologize if this is a silly question. I'd like a script that goes through all 19,000 search results pages and scrapes each page for all of the urls. I've got all of the scrapping working but can't figure out how to deal with the fact that the page uses AJAX to paginate. Usually I'd just make a loop with the url to capture each search result but that's not possible. Here's the page: http://www.heritage.org/research/all-research.aspx?nomobile&categories=report
This is the script I have so far:
with io.open('heritageURLs.txt', 'a', encoding='utf8') as logfile:
page = urllib2.urlopen("http://www.heritage.org/research/all-research.aspx?nomobile&categories=report")
soup = BeautifulSoup(page)
snippet = soup.find_all('a', attrs={'item-title'})
for a in snippet:
logfile.write ("http://www.heritage.org" + a.get('href') + "\n")
print "Done collecting urls"
Obviously, it scrapes the first page of results and nothing more.
And I have looked at a few related questions but none seem to use Python or at least not in a way that I can understand. Thank you in advance for your help.
For the sake of completeness, while you may try accessing the POST request and to find a way round to access to next page, like I suggested in my comment, if an alternative is possible, using Selenium will be quite easy to achieve what you want.
Here is a simple solution using Selenium for your question:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from time import sleep
# uncomment if using Firefox web browser
driver = webdriver.Firefox()
# uncomment if using Phantomjs
#driver = webdriver.PhantomJS()
url = 'http://www.heritage.org/research/all-research.aspx?nomobile&categories=report'
driver.get(url)
# set initial page count
pages = 1
with open('heritageURLs.txt', 'w') as f:
while True:
try:
# sleep here to allow time for page load
sleep(5)
# grab the Next button if it exists
btn_next = driver.find_element_by_class_name('next')
# find all item-title a href and write to file
links = driver.find_elements_by_class_name('item-title')
print "Page: {} -- {} urls to write...".format(pages, len(links))
for link in links:
f.write(link.get_attribute('href')+'\n')
# Exit if no more Next button is found, ie. last page
if btn_next is None:
print "crawling completed."
exit(-1)
# otherwise click the Next button and repeat crawling the urls
pages += 1
btn_next.send_keys(Keys.RETURN)
# you should specify the exception here
except:
print "Error found, crawling stopped"
exit(-1)
Hope this helps.
