我在通过selenium python抓取内容时出错

Question

我正在上抓取作业结果的标题https://www.indeed.ae/jobs-in-dubai通过硒。我想。文本不起作用。我正在通过selenium运行代码，该代码进入主网站，输入选择性关键字，然后从结果中抓取所有标题。但是我有错误，我该如何解决这个错误

这是我的代码

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()

我得到以下错误

您找不到标题，因为您从resultsCol中获取了所有div。这意味着有些div有标题，有些则没有。

试试这个：

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()

将标题作为输出：
