未知的 Python Selenium 错误：Traceback（最近一次调用最后一次）：文件“D:\pythonProject\webscraping.py”，第 17 行，在<module>

Question

I am making this little program for Minecraft as a little program for fun and practicing python. I am using selenium and when I was trying to get the name of something in the HTML webpage with find_element it gave me this massive error code:

Traceback (most recent call last):
  File "D:\pythonProject\webscraping.py", line 17, in <module>
    username = driver.find_element(By.NAME, 'text-shadow: 1px 1px #eee; color:#3CE6E6')

Here is my code for the program:

from tqdm import tqdm
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
import time

x=Service('C:\Program Files (x86)\chromedriver.exe')
driver = webdriver.Chrome(service=x)

pbar = tqdm(range(10))

for i in pbar:
    time.sleep(0.3)
    pbar.set_description("loading program")
PlankeName = input("Whos Planke Page would you like to view? ")
UserPlankeLink = "https://plancke.io/hypixel/player/stats/" + PlankeName
driver.get(UserPlankeLink)

username = driver.find_element(By.NAME, 'text-shadow: 1px 1px #eee; color:#3CE6E6')
print(username)
print("You are currently Viewing " + driver.title)

Please help!

Answer 1

Your error is NoSuchElementException because your element is not found. This exists because your identifier is wrong, or the page has not fully loaded yet.

I've had a look at your page - and your identifier is wrong. But - It's also a poorly described website so it's a tricky one for beginners.

I updated it to use this xpath:

//div[h3[text()='Player Information']]//span[text()]

That is: From the div , which has the h3 inside it and where that h3 has text=player information - Get the span which has any text.

Using this this code:

driver = webdriver.Chrome() # note i modified this to my driver - reset to yours
driver.implicitly_wait(10)

PlankeName = input("Whos Planke Page would you like to view? ")
UserPlankeLink = "https://plancke.io/hypixel/player/stats/" + PlankeName
driver.get(UserPlankeLink)

username = driver.find_element(By.XPATH, "//div[h3[text()='Player Information']]//span[text()]")
print(username.text)
print("You are currently Viewing " + driver.title)

When entering the input test as the players name, I get output:

You are currently Viewing Test's Stats | Plancke
