selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".ui flu~"}

Question

This is the code I use:

import requests as r, sys as sus, bs4 as bs, webbrowser as wb
from selenium import webdriver as wd

dr = wd.Chrome()

b = r.get("https://uupdump.net/fetchupd.php?arch=amd64&ring=wif&build=latest").text
s = bs.BeautifulSoup(b, features="html.parser")

if "/selectlang.php?id=" in b:
    l = b.split("/selectlang.php?id=")[1].split('"')[0]
    u = f"https://uupdump.net/download.php?id={l}&pack=es-es&edition=professional"
    print(u)
    b = r.get(u).text
    s = bs.BeautifulSoup(b, features="html.parser")
    print(s)
    dr.get(u)
    b = dr.find_element_by_class_name('ui fluid right labeled icon primary button')

And this is the error:

uupdump.py:17: DeprecationWarning: find_element_by_* commands are deprecated. Please use find_element() instead
  b = dr.find_element_by_class_name('ui fluid right labeled icon primary button')

Help.

What else to say? "It looks like your post is mostly code"

Answer 1

To find the specific button element that you want you can do:

b = dr.find_elements_by_class_name('primary')[-1]

instead of

b = dr.find_element_by_class_name('ui fluid right labeled icon primary button')

Because the class name that you copied is a compilation of classnames for that object. Each class name is separated by a space. Therefore using the most unique identifier 'primary' we are able to narrow the elements down to 3 and see that the element that you want is the last one.

and then do

b.click()

to click on that element.

Though you may want to wait for that element to load on the page.

Answer 2

As per the HTML:

To identify the clickable element with text as Create download package you can use either of the following Locator Strategies :

• Using xpath :

   b = dr.find_element(By.XPATH, "//button[@class='ui fluid right labeled icon primary button' and contains(., 'Create download package')]")

Ideally to click on the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies :

• Using XPATH :

   b = WebDriverWait(dr, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@class='ui fluid right labeled icon primary button' and contains(., 'Create download package')]")))

• Note : You have to add the following imports:

   from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC
