如何在Python Selenium中使用XPath访问节点的孙子节点？

# 假设driver是你的WebDriver实例
span_element = driver.find_element_by_xpath('//div/p/span')

# 假设div_element是<div>元素的引用
span_element = div_element.find_element_by_xpath('./p/span')

from selenium import webdriver

# 初始化WebDriver（这里以Chrome为例）
driver = webdriver.Chrome()

# 打开一个网页
driver.get('http://example.com')

# 使用XPath找到<div>元素
div_element = driver.find_element_by_xpath('//div[@id="grandparent"]')

# 从<div>元素出发，找到孙子节点<span>
span_element = div_element.find_element_by_xpath('./p/span')

# 打印孙子节点的文本内容
print(span_element.text)

# 关闭浏览器
driver.quit()

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

# 等待元素出现
wait = WebDriverWait(driver, 10)
span_element = wait.until(EC.presence_of_element_located((By.XPATH, '//div[@id="grandparent"]/p/span')))
