How to load all entries in an infinite scroll at once to parse the HTML in python

Question

I am trying to extract information from this page. The page loads 10 items at a time, and I need to scroll to load all entries (for a total of 100). I am able to parse the H

Answer 1

This you won't be able to do with requests and BeautifulSoup as the page that you want to extract the information from loads the rest of the entries through JS when you scroll down. You can do this using selenium which opens a real browser and you can pass page down key press events programmatically. Watch this video to see the action. http://www.youtube.com/watch?v=g54xYVMojos

Below is the script that extracts all the 100 post titles using selenium.

import time

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

browser = webdriver.Chrome()

browser.get("https://medium.com/top-100/december-2013")
time.sleep(1)

elem = browser.find_element_by_tag_name("body")

no_of_pagedowns = 20

while no_of_pagedowns:
    elem.send_keys(Keys.PAGE_DOWN)
    time.sleep(0.2)
    no_of_pagedowns-=1

post_elems = browser.find_elements_by_class_name("post-item-title")

for post in post_elems:
    print post.text
