如何在selenium中使用字段集中的图例定位单选按钮

from selenium import webdriver
from selenium.webdriver.common.by import By

driver = webdriver.Chrome()  # 使用Chrome浏览器，需提前安装ChromeDriver并配置环境变量
driver.get("https://example.com")  # 替换为目标网页的URL

legend_text = "图例文本"  # 替换为字段集的图例文本
legend_element = driver.find_element(By.XPATH, f"//legend[text()='{legend_text}']")

fieldset_element = legend_element.find_element(By.XPATH, "./parent::fieldset")
radio_buttons = fieldset_element.find_elements(By.XPATH, ".//input[@type='radio']")

for radio_button in radio_buttons:
    # 根据单选按钮的属性、文本等进行判断和操作
    if radio_button.get_attribute("value") == "option1":
        radio_button.click()  # 选择该单选按钮
        break  # 可根据实际情况决定是否终止循环
