Get Youtube's most replayed data through web scraping-CodePudding

I want to get data out of youtube's "heat-map" feature, which is present in videos with certain features. This is an example. I want to retrieve this data somehow yet Youtube API's don't provide it and, this api doesn't always work. I'm aware they probably use the same approach, but I want to be able to have a reliable source of information. As of this approach (web-scrapping), I have tried using selenium, with the XPath of the element (you can find in the html of the video if you search for the class ytp-heat-map-path, like this):

driver = webdriver.Firefox()
driver.get("https://www.youtube.com/watch?v=09wcDevb1q4")
        
while len(driver.find_elements(By.XPATH,"/html/body/ytd-app/div[1]/ytd-page-manager/ytd-watch-flexy/div[3]/div/ytd-player/div/div/div[31]/div[1]/div[1]/div[2]/svg/defs/clipPath/path")) == 0:
            pass


a = driver.find_element(By.XPATH,"/html/body/ytd-app/div[1]/ytd-page-manager/ytd-watch-flexy/div[3]/div/ytd-player/div/div/div[31]/div[1]/div[1]/div[2]/svg/defs/clipPath/path")

I have also tried with beautifulSoup, finding the class:

mydivs = soup.find_all("path", {"class": "ytp-heat-map-path"})

None of them can find the data. I'm happy to find a solution to this with web scrapping or any other method. Thanks.

That desired data is under an attribute value of d with path tag. So you can try the next example.

from selenium import webdriver
import time
from bs4 import BeautifulSoup
from selenium.webdriver.chrome.service import Service

#You change this portion into Firefox instead
webdriver_service = Service("./chromedriver") 
driver = webdriver.Chrome(service=webdriver_service)


driver.get('https://www.youtube.com/watch?v=09wcDevb1q4')
driver.maximize_window()
time.sleep(8)


soup = BeautifulSoup(driver.page_source,"html.parser")

mydivs = soup.find("path", {"class": "ytp-heat-map-path"}).get('d')
print(mydivs)

Output:

I want to be able to have a reliable source of information

Note that by web-scraping you can't have a better stability than my open-source API you are referring to. I guess the stability issue you are referring to is that when web-scraping is abused, YouTube servers suspend temporarily your ability to retrieve the most replayed data.

As far as I know nobody using their own instance of my API for their own private usage have faced this issue. So I guess you only used the official instance of my API which, by its numerous users, abuses from YouTube UI servers, and so it is regularly suspended.

So the solutions are:

To try with your own private instance of my API.
Otherwise just directly parse the ytInitialData JavaScript variable in the HTML, as I did in my API, that way you don't need a JavaScript interpreter such as Selenium.
