Python Selenium - StaleElementReferenceException - WebDriverWait doesn't work

I'm trying to web scrape some information from a website. The loop works the first time but the 2nd time the error occurs. I've tried several approaches to solve it with implicit wait or WebDriverUntil but the exception continues to appear. Would you give me a hand?
Here is the code:
website = 'https://www.elempleo.com/co/ofertas-empleo/55-6-millones?'
driver = webdriver.Chrome(path)
driver.get(website)
empleos = driver.find_elements_by_tag_name('div.result-list.js-result-list.js-results-container')
data = []
i = 0
data = empleos[0].text.splitlines()
while i < 4:
data.append(empleos[0].text.splitlines())
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
siguiente = driver.find_elements_by_tag_name('a.js-btn-next')
siguiente[0].click()
i += 1
I tried using:
siguiente = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.TAG_NAME, "a.js-btn-next")))
and
driver.implicitly_wait(10) with different times but it didn't work

How to scroll correctly in a dynamically-loading webpage with Selenium?

Here's the link of the website : website
I would like to have all the links of th hotels in this location.
Here's my script :
import pandas as pd
import numpy as np
from selenium import webdriver
import time
PATH = "driver\chromedriver.exe"
options = webdriver.ChromeOptions()
options.add_argument("--disable-gpu")
options.add_argument("--window-size=1200,900")
options.add_argument('enable-logging')
driver = webdriver.Chrome(options=options, executable_path=PATH)
driver.get('https://fr.hotels.com/search.do?destination-id=10398359&q-check-in=2021-06-24&q-check-out=2021-06-25&q-rooms=1&q-room-0-adults=2&q-room-0-children=0&sort-order=BEST_SELLER')
cookie = driver.find_element_by_xpath('//button[#class="uolsaJ"]')
try:
cookie.click()
except:
pass
for i in range(30):
driver.execute_script("window.scrollBy(0, 1000)")
time.sleep(5)
time.sleep(5)
my_elems = driver.find_elements_by_xpath('//a[#class="_61P-R0"]')
links = [my_elem.get_attribute("href") for my_elem in my_elems]
X = np.array(links)
print(X.shape)
#driver.close()
But I cannot find a way to tell the script : scroll down until there is nothing more to scroll.
I tried to change this parameters :
for i in range(30):
driver.execute_script("window.scrollBy(0, 1000)")
time.sleep(30)
I changed the time.sleep(), the number 1000 and so on but my output keep changing and not in the right way.
output
As you can see, I have scraped a lot of numbers differents. How to make my script scraping a same amout each time ? Not necessarily each links but at last a stable number.
Here it scroll and at one point it seems blocked and scrape all the links it has at the moment. That's not appropriate.

There are several issues here.
You are getting the elements and their links only AFTER you finished scrolling while you should do that inside the scrolling loop.
You should wait until the cookies alert is appearing to close it.
You can scroll until the footer element is presented.
Something like this:
import pandas as pd
import numpy as np
from selenium import webdriver
import time
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
PATH = "driver\chromedriver.exe"
options = webdriver.ChromeOptions()
options.add_argument("--disable-gpu")
options.add_argument("--window-size=1200,900")
options.add_argument('enable-logging')
driver = webdriver.Chrome(options=options, executable_path=PATH)
wait = WebDriverWait(driver, 20)
driver.get('https://fr.hotels.com/search.do?destination-id=10398359&q-check-in=2021-06-24&q-check-out=2021-06-25&q-rooms=1&q-room-0-adults=2&q-room-0-children=0&sort-order=BEST_SELLER')
wait.until(EC.visibility_of_element_located((By.XPATH, '//button[#class="uolsaJ"]'))).click()
def is_element_visible(xpath):
wait1 = WebDriverWait(driver, 2)
try:
wait1.until(EC.visibility_of_element_located((By.XPATH, xpath)))
return True
except Exception:
return False
while not is_element_visible("//footer[#id='footer']"):
my_elems = driver.find_elements_by_xpath('//a[#class="_61P-R0"]')
links = [my_elem.get_attribute("href") for my_elem in my_elems]
X = np.array(links)
print(X.shape)
driver.execute_script("window.scrollBy(0, 1000)")
time.sleep(5)
#driver.close()

You can try this by directly calling the DOM and locate some element that will be only at the bottom of the page with .is_displayed() selenium method which returns true/false:
# https://stackoverflow.com/a/57076690/15164646
while True:
# it will be returning false until the element is located
# "#message" id = "No more results" at the bottom of the YouTube search
end_result = driver.find_element_by_css_selector('#message').is_displayed()
driver.execute_script("var scrollingElement = (document.scrollingElement || document.body);scrollingElement.scrollTop = scrollingElement.scrollHeight;")
# further code below
# once the element is found it returns True. If so, it will break out of the while loop
if end_result == True:
break
I wrote a blog post where I used this method to scrape YouTube Search.

Next Page Iteration in Selenium/BeautfulSoup for Scraping E-Commerce Website

I'm scraping an E-Commerce website, Lazada using Selenium and bs4, I manage to scrape on the 1st page but I unable to iterate to the next page. What I'm tyring to achieve is to scrape the whole pages based on the categories I've selected.
Here what I've tried :
# Run the argument with incognito
option = webdriver.ChromeOptions()
option.add_argument(' — incognito')
driver = webdriver.Chrome(executable_path='chromedriver', chrome_options=option)
driver.get('https://www.lazada.com.my/')
driver.maximize_window()
# Select category item #
element = driver.find_elements_by_class_name('card-categories-li-content')[0]
webdriver.ActionChains(driver).move_to_element(element).click(element).perform()
t = 10
try:
WebDriverWait(driver,t).until(EC.visibility_of_element_located((By.ID,"a2o4k.searchlistcategory.0.i0.460b6883jV3Y0q")))
except TimeoutException:
print('Page Refresh!')
driver.refresh()
element = driver.find_elements_by_class_name('card-categories-li-content')[0]
webdriver.ActionChains(driver).move_to_element(element).click(element).perform()
print('Page Load!')
#Soup and select element
def getData(np):
soup = bs(driver.page_source, "lxml")
product_containers = soup.findAll("div", class_='c2prKC')
for p in product_containers:
title = (p.find(class_='c16H9d').text)#title
selling_price = (p.find(class_='c13VH6').text)#selling price
try:
original_price=(p.find("del", class_='c13VH6').text)#original price
except:
original_price = "-1"
if p.find("i", class_='ic-dynamic-badge ic-dynamic-badge-freeShipping ic-dynamic-group-2'):
freeShipping = 1
else:
freeShipping = 0
try:
discount = (p.find("span", class_='c1hkC1').text)
except:
discount ="-1"
if p.find(("div", {'class':['c16H9d']})):
url = "https:"+(p.find("a").get("href"))
else:
url = "-1"
nextpage_elements = driver.find_elements_by_class_name('ant-pagination-next')[0]
np=webdriver.ActionChains(driver).move_to_element(nextpage_elements).click(nextpage_elements).perform()
print("- -"*30)
toSave = [title,selling_price,original_price,freeShipping,discount,url]
print(toSave)
writerows(toSave,filename)
getData(np)

The problem might be that the driver is trying to click the button before the element is even loaded correctly.
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome(PATH, chrome_options=option)
# use this code after driver initialization
# this is make the driver wait 5 seconds for the page to load.
driver.implicitly_wait(5)
url = "https://www.lazada.com.ph/catalog/?q=phone&_keyori=ss&from=input&spm=a2o4l.home.search.go.239e359dTYxZXo"
driver.get(url)
next_page_path = "//ul[#class='ant-pagination ']//li[#class=' ant-pagination-next']"
# the following code will wait 5 seconds for
# element to become clickable
# and then try clicking the element.
try:
next_page = WebDriverWait(driver, 5).until(
EC.element_to_be_clickable((By.XPATH, next_page_path)))
next_page.click()
except Exception as e:
print(e)
EDIT 1
Changed the code to make the driver wait for the element to become clickable. You can add this code inside a while loop for iterating multiple times and break the loop if the button is not found and is not clickable.

How to print the open pdf link from using Selenium in Python?

I am not able to print the link of the final pdf which is opening after running the given code
from selenium import webdriver
from selenium.webdriver.support import ui
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
def page_is_loaded(driver):
return driver.find_element_by_tag_name("body")!= None
def check_exists_by_text(text):
try:
driver.find_element_by_link_text(text)
except NoSuchElementException:
return False
return True
driver = webdriver.Chrome("C:/Users/Roshan/Desktop/sbi/chromedriver")
driver.maximize_window()
driver.get("http://www.careratings.com/brief-rationale.aspx")
wait = ui.WebDriverWait(driver,10)
wait.until(page_is_loaded)
location_field = driver.find_element_by_name("txtfromdate")
location_field.send_keys("2019-05-06")
last_date = driver.find_element_by_name("txttodate")
last_date.send_keys("2019-05-21")
driver.find_element_by_xpath("//input[#name='btn_submit']").click()
if check_exists_by_text('Reliance Capital Limited'):
elm =driver.find_element_by_link_text('Reliance Capital Limited')
driver.implicitly_wait(5)
elm.click()
driver.implicitly_wait(50)
#time.sleep(5)
#driver.quit()
else :
print("Company is not rated in the given Date range")
I am expecting the actual output is the link of this pdf :
"http://www.careratings.com/upload/CompanyFiles/PR/Reliance%20Capital%20Ltd.-05-18-2019.pdf"
but I do not know how to print this link

You need to find all elements in table, then extract data from them.
from selenium import webdriver
import os
# setup path to chrome driver
chrome_driver = os.getcwd() + '/chromedriver'
# initialise chrome driver
browser = webdriver.Chrome(chrome_driver)
# load url
browser.get('http://www.careratings.com/brief-rationale.aspx')
# setup date range
location_field = browser.find_element_by_name("txtfromdate")
location_field.send_keys("2019-05-06")
last_date = browser.find_element_by_name("txttodate")
last_date.send_keys("2019-05-21")
browser.find_element_by_xpath("//input[#name='btn_submit']").click()
# get all data rows
content = browser.find_elements_by_xpath('//*[#id="divManagementSpeak"]/table/tbody/tr/td/a')
# get text and href link from each element
collected_data = []
for item in content:
url = item.get_attribute("href")
description = item.get_attribute("innerText")
collected_data.append((url, description ))
Output:
('http://www.careratings.com/upload/CompanyFiles/PR/Ashwini%20Frozen%20Foods-05-21-2019.pdf', 'Ashwini Frozen Foods')
('http://www.careratings.com/upload/CompanyFiles/PR/Vanita%20Cold%20Storage-05-21-2019.pdf', 'Vanita Cold Storage')
and so on

I would say you just need to put this line:
pdf_link = elm.get_attribute("href")

Just check out the below image. You have missed one important part to click on. When you enter some text in that inputbox, there is a dropdown projected downward displaying the search results available in their stock to choose from. Once you click on that, the rest are as it is.
Try the following script:
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
url = "http://www.careratings.com/brief-rationale.aspx"
with webdriver.Chrome() as driver:
driver.get(url)
wait = WebDriverWait(driver,10)
location_field = wait.until(EC.presence_of_element_located((By.NAME, "txtfromdate")))
location_field.send_keys("2019-05-06")
last_date = wait.until(EC.presence_of_element_located((By.NAME, "txttodate")))
last_date.send_keys("2019-05-21")
input_search = wait.until(EC.presence_of_element_located((By.NAME, "txtSearchCompany_brief")))
input_search.send_keys('Reliance Capital Limited')
time.sleep(3) #could not get rid of this hardcoded delay to make the script work
wait.until(EC.presence_of_element_located((By.CSS_SELECTOR,"[onclick*='Reliance Capital Limited']"))).click()
# time.sleep(2) #activate this line in case the script behaves otherwise
wait.until(EC.presence_of_element_located((By.CSS_SELECTOR,"input[name='btn_submit']"))).click()
for item in wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR,"table tr td > a[href$='.pdf']"))):
print(item.get_attribute("href"))

Python - Selenium next page

I am trying to make a scraping application to scrape Hants.gov.uk and right now I am working on it just clicking the pages instead of scraping. When it gets to the last row on page 1 it just stopped, so what I did was make it click button "Next Page" but first it has to go back to the original URL. It clicks page 2, but after page 2 is scraped it doesn't go to page 3, it just restarts page 2.
Can somebody help me fix this issue?
Code:
import time
import config # Don't worry about this. This is an external file to make a DB
import urllib.request
from bs4 import BeautifulSoup
from selenium import webdriver
url = "https://planning.hants.gov.uk/SearchResults.aspx?RecentDecisions=True"

As per the url https://planning.hants.gov.uk/SearchResults.aspx?RecentDecisions=True to click through all the pages you can use the following solution:
Code Block:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://planning.hants.gov.uk/SearchResults.aspx?RecentDecisions=True')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "mainContentPlaceHolder_btnAccept"))).click()
numLinks = len(WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div#ctl00_mainContentPlaceHolder_lvResults_topPager div.rdpWrap.rdpNumPart>a"))))
print(numLinks)
for i in range(numLinks):
print("Perform your scrapping here on page {}".format(str(i+1)))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[#id='ctl00_mainContentPlaceHolder_lvResults_topPager']//div[#class='rdpWrap rdpNumPart']//a[#class='rdpCurrentPage']/span//following::span[1]"))).click()
driver.quit()
Console Output:

Perform your scrapping here on page 3
Perform your scrapping here on page 4
Perform your scrapping here on page 5

hi #Feitan Portor you have written the code absolutely perfect the only reason that you are redirected back to the first page is because you have given url = driver.current_url in the last for loop where it is the url that remains static and only the java script that instigates the next click event so just remove url = driver.current_url and driver.get(url)
and you are good to go i have tested my self
also to get the current page that your scraper is in just add this part in the for loop so you will get to know where your scraper is :
ss = driver.find_element_by_class_name('rdpCurrentPage').text
print(ss)
Hope this solves your confusion
