我在通過 selenium python 抓取內容時遇到錯誤

Question

我正在通過 selenium 在https://www.indeed.ae/jobs-in-dubai上抓取工作結果的標題。 我認為.text 不起作用。 我正在通過 selenium 其中 go 將代碼運行到主網站，輸入選擇性關鍵字，然后從結果中刮掉所有標題。 但我收到錯誤，我該如何解決這個錯誤

這是我的代碼

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
from selenium.webdriver.common.keys import Keys

Path = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(Path)

driver.get("https://indeed.ae/")
print(driver.title)
search = driver.find_element_by_name("l")
search.send_keys("Dubai")
search.send_keys(Keys.RETURN)


try:
    td = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "resultsCol"))
    )
    divs = td.find_elements_by_tag_name("div")
    for div in divs:
        header = div.find_element_by_class_name("title")
        print(header)
finally:
    driver.quit()

driver.quit()

我收到以下錯誤

您找不到標題，因為您從 resultsCol 中獲取了所有 div。 這意味着有些 div 有標題，有些沒有。

嘗試這個：

try:
    td = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "resultsCol"))
    )
    divs = td.find_elements_by_tag_name("div")
    #print(divs)
    for div in divs:
        try:
            header = div.find_element_by_class_name("title")
            print(header.text)
        except:
            continue
finally:
    driver.quit()

driver.quit()

標題為 output：
