Webdriver selenium - can't find any element from TradingView - python

I'm new to using Selenium but I watched enough videos and followed enough articles to know something is missing. I'm trying to get values from TradingView but the problem I'm running into is that I simply can't find any of the elements, not by Xpath or Css. I went ahead and tried to do a simple visibility element test as shown in the code below and to my surprise it times out.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
# Stops the UI interface (chrome browser) from popping up
# chrome_options.add_argument("--headless")
driver = webdriver.Chrome(executable_path='c:\se\chromedriver.exe', options=chrome_options)
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
import time
driver.get("https://www.tradingview.com/chart/")
timeout = 20
try:
WebDriverWait(driver, timeout).until(EC.visibility_of_element_located((By.XPATH, "/html/body/div[1]")))
print("Page loaded")
except TimeoutException:
print("Timed out waiting for page to load")
driver.quit()
I tried to click on one of the chart buttons too using the following and that doesn't work either. I noticed that unlike many other websites for Tradingview the elements don't have names and don't generate a relative path (only full) using Xpath.
driver.find.element_by_xpath('/html/body/div[2]/div[5]/div/div[2]/div/div/div/div/div[4]').click()
Any help is greatly appreciated!

I think there must be an issue with xpath.
When I try to click the AAPL button it is working for me.
The xpath I used is:
(//div[contains(text(),'AAPL')])[1]
If you specify exactly which element to be clicked I will try.
And also be familiar with the concept of frames because these type of websites has lot of frames in it.

Handling "Accept all cookie" popup with selenium when selector is unknown

I have a python script, It look like this.
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.select import Select
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from os import path
import time
# Tried this code
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
browser = webdriver.Chrome(ChromeDriverManager().install(), chrome_options=chrome_options)
links = ["https://www.henleyglobal.com/", "https://markets.ft.com/data"]
for link in links:
browser.get(link)
#WebDriverWait(browser, 20).until(EC.url_changes(link))
#How do I disable/Ignore/remove/escape this "Accept all cookie" popup and then access the website to scrape data?
browser.quit()
So each website in the links array displays an "Accept all cookie" popup after navigating to the site. check the below image.
I have tried many ways nothing works, Check the one after imports
How do I exit/pass/escape this popup and then access the website to scrape data?
If you open your page in a new browser you'll note the page fully loads, then, a moment later your popup appears. The default wait strategy in selenium is just that the page is loaded.
One way to handle this is to simply inspect the page and find the xpath of the popup window. The below code should work for that.
browser.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS)
if link == 'https://www.henleyglobal.com/':
browser.findElement(By.XPATH("/html/body/div[7]/div/div/div/div[2]/div/div[2]/button[2]")).click()
else:
browser.findElement(By.XPATH("/html/body/div[4]/div/div/div[2]/div[2]/a")).click()
The code is waiting until the element of the pop-up is clickable and then clicking it.
For unknown sites you could try:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--disable-notifications")
webdriver.Chrome(os.path.join(path, 'chromedriver'), chrome_options=chrome_options)
generally, you can not use some universal locator that will match the "Accept cookies" buttons for each and every web site in the world.
Even here, you have 2 different sites and the elements you need to click are totally different on these sites.
For https://www.henleyglobal.com/ site the correct locator may be something like this CSS Selector .confirmation button.primary-btn while for https://markets.ft.com/data site I'd advise to use CSS Selector .o-cookie-message__actions a.o-cookie-message__button.
These 2 elements are totally different: the first one is button while the second is a, they have totally different class names and all other attributes.
You may thing about the Accept text. It seems to be common, so you could use this XPath //*[contains(text(),'Accept')] but even this will not work since on the first page it matches 2 elements while the accept cookies element is the second between them...
So, there is no General locators, you will have to define separate locators for each page.
Again, for https://www.henleyglobal.com/ I would prefer
driver.find_element(By.CSS_SELECTOR, ".confirmation button.primary-btn").click()
While for the second page https://markets.ft.com/data I would prefer this
driver.find_element(By.CSS_SELECTOR, ".o-cookie-message__actions a.o-cookie-message__button").click()
Also, generally we always use WebDriverWait expected_conditions explicit waits, so the code will be as following:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
wait = WebDriverWait(driver, 10)
# for the first page
wait.until(EC.element_to_be_clickable((By.XPATH, ".confirmation button.primary-btn"))).click()
# for the second page
wait.until(EC.element_to_be_clickable((By.XPATH, ".o-cookie-message__actions a.o-cookie-message__button"))).click()

Can't select element from page [Selenium[

I have tried to scrap info from that site - specifically, from a table. Every time I occur, info that elements doesn't exist.
https://polygonscan.com/token/0x64a795562b02830ea4e43992e761c96d208fc58d
I try to add time.slep(5) to my code or scrolling down function to load all element - ineffective.
Do you have any advice for me?

I added code in regard to your request. So my main goal is to scrap content from the table at this site. I add Explicit Waits to my code and still I can't select anything from that table - it's looking like the script doesn't see anything from that area.
One way to try solve it, its using the Xpath of the element or the relative position of the same, to make Selenium, get allways the same "line" of position to return the "value" of the information that you are searching.
Ex1:find_element(:xpath,"//*[#id="wmd-input"]")#in that case it's the input of this check box.
If it doesnt work, try this one.
Ex2: browser.implicitly_wait(30) #makes a timer to load all the informations from the web to your machine.

Selenium not able to find particular elements on slow loading page

I am attempting to scrape the website basketball-reference and am running into an issue I can't seem to solve. I am trying to grab the box score element for each game played. This is something I was able to easily do with urlopen but b/c other portions of the site require Selenium I thought I would rewrite the entire process with Selenium
Issue seems to be that even if I wait to scrape until I to see the first element load using WebDriverWait, when I then move forward to grabbing the elements I get nothing returned.
One thing I found interesting is if I did a full site print using my results from urlopen w/ something like print (uClient.read()) I would get roughly 300 more lines of html after beautifying compared to doing the same with print (driver.page_source). Even if I put an ImplicitlyWait set for 5 minutes.
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome('/usr/local/bin/chromedriver')
driver.wait = WebDriverWait(driver, 10)
driver.get('https://www.basketball-reference.com/boxscores/')
driver.wait.until(EC.presence_of_element_located((By.XPATH,'//*[#id="content"]/div[3]/div[1]')))
box = driver.find_elements_by_class_name('game_summary expanded nohover')
print (box)
driver.quit()
Try the below code, it is working in my computer. Do let me know if you still face problem.
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()
driver.wait = WebDriverWait(driver, 60)
driver.get('https://www.basketball-reference.com/boxscores/')
driver.wait.until(EC.presence_of_element_located((By.XPATH, '//*[#id="content"]/div[3]/div[1]')))
boxes = driver.wait.until(
EC.presence_of_all_elements_located((By.XPATH, "//div[#class=\"game_summary expanded nohover\"]")))
print("Number of Elements Located : ", len(boxes))
for box in boxes:
print(box.text)
print("-----------")
driver.quit()
If it resolves your problem then please mark it as answer. Thanks
Actually the site doesn't require selenium at all. All the data is there through a simple requests (it's just in the Comments of the html, would just need to parse that). Secondly, you can grab the box scores quite easily with pandas
import pandas as pd
dfs = pd.read_html('https://www.basketball-reference.com/boxscores/')
for idx, table in enumerate(dfs[:-2]):
print (table)
if (idx+1)%3 == 0:
print("-----------")

Unable to use "explicit wait" in the right way

I've written a script using python with selenium to click on some links listed in the sidebar of google maps. When any of the items get clicked, the related information attached to each lead shows up in the right sided area. The script is doing fine. However, I've used hardcoded delay to do the job. How can I get rid of hardcoded delay by achieving the same with explicit wait. Thanks in advance.
Link to the site: website
The script I'm trying with:
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
link = "replace_with_above_link"
driver = webdriver.Chrome()
driver.get(link)
wait = WebDriverWait(driver, 10)
for item in wait.until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "[id^='rlimg0_']"))):
item.location
time.sleep(3) #wish to try with explicit wait but can't find any idea
item.click()
driver.quit()
I tried with wait.until(EC.staleness_of(item)) instead of hardcoded delay but no luck.
If you want to wait until new data displayed after each clcik you may try below:
for item in wait.until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "[id^='rlimg0_']"))):
div = driver.find_element_by_xpath("//div[#class='xpdopen']")
item.location
item.click()
wait.until(EC.staleness_of(div))

Selenium: Dynamically loaded page causes automatic scrolling to fail

I'm using Selenium for Python to navigate a dynamic webpage (link).
I would like to automatically scroll down to a y-point on the page. I have tried various ways to code this, which seem to work on other pages, but not on this particular webpage.
Some examples of my efforts that don't seem to work for Firefox with Selenium:
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://en.boerse-frankfurt.de/etp/Deka-Oekom-Euro-Nachhaltigkeit-UCITS-ETF-DE000ETFL474")
By scrolling to a y-position:
driver.execute_script("window.scrollTo(0, 1400);")
Or by finding an element:
try:
find_scrollpoint = driver.find_element_by_xpath("//*[#id='main-wrapper']/div[10]/div/div[1]/div[1]")
except:
pass
else:
scrollpoint = find_scrollpoint.location["y"]
driver.execute_script("window.scrollTo(0, scrollpoint);")
Questions:
What could be some unusual circumstances on webpages such as this, where this very typical scrollTo code may fail?
What can possibly be done to mitigate it? Perhaps keypresses to scroll down – but it would still have to know when to stop pressing down.
It is just quite a dynamic page. I would wait for this specific element to be visible and then scroll into it's view. This works for me:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
driver = webdriver.Firefox()
driver.get("http://en.boerse-frankfurt.de/etp/Deka-Oekom-Euro-Nachhaltigkeit-UCITS-ETF-DE000ETFL474")
wait = WebDriverWait(driver, 10)
elm = wait.until(EC.visibility_of_element_located((By.XPATH, "//*[#id='main-wrapper']/div[10]/div/div[1]/div[1]")))
driver.execute_script("arguments[0].scrollIntoView();", elm)
