如何点击之前找到的同级 - python selenium

Question

是否有机会单击上一个找到的同级来打开那里的链接？

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By  
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait
import time
import openpyxl



# Load Excel data
excel_data = openpyxl.load_workbook("C:\Automatizace\data.xlsx")
sht = excel_data.active
cell_vz = sht.cell(row=2, column=2).value


try:
   wait = WebDriverWait(driver, 20)
   find_user = wait.until(EC.presence_of_element_located((By.XPATH, f"//*[contains(text(),     '{cell_vz}')]")))


   previous_sibling = find_user.find_element(By.XPATH, "preceding-sibling::*[2]")
   previous_sibling.click()
   print("Najito: ", previous_sibling.text)



except Exception as error:
    print("Chyba při hledání uživatele:", error)

time.sleep(10)

previous_sibling.click()

不适用于此...

网站结构：

 <tr>
    <td>
      <a href="something">text</a>
    </td>
    <td></td> //this is what I need to click on
    <td></td>
    <td></td> //data from cell_vz
    <td></td>
    <td></td>
    <td></td>
    </tr>

Answer 1

看起来问题已经发生，因为

preceding-sibling

的使用不正确。 为了工作，你应该链接两个选择器

find_user = wait.until(EC.presence_of_element_located((By.XPATH, f"//*[contains(text(), '{cell_vz}')]//preceding-sibling::*[2]")))

我为您的案例创建了示例，当使用

id=2

单击所需元素时，会使用

id=1

触发元素上的背景颜色更改

driver.get("https://inputnum.w3spaces.com/saved-from-Tryit-2023-08-17-a93u0.html")

td_2 = driver.find_element(By.XPATH, "//*[@id='1']//preceding-sibling::*[2]")
td_2.click()

如果仍然不起作用，可能还有其他原因导致您无法点击。
