Selenium中动态变量拼接定位元素失效问题求助

问题现象 #

静态定位代码可正常运行：

monday_div = driver.find_element(By.XPATH, '//*[@id="GXPMonday"]')

但使用动态变量循环定位的代码执行失败：

weekdays = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']

for day in weekdays:
    main_day_div = driver.find_elements(By.XPATH, '//*[@id="GXP' + day + '"]')

报错信息：

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="GXPMonday"]

解决方案 #

最终可行的代码如下：

weekdays = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
main_day_div_list = []
all_div_list = []

# 循环定位每一天的父容器并存入列表
for day in weekdays:
     main_day_divs = driver.find_element(By.XPATH, '//*[@id="GXP' + day + '"]')
     main_day_div_list.append(main_day_divs)

# 遍历父容器，获取每个容器下的GXPEntry元素
for element in main_day_div_list:
    entries = element.find_elements(By.CLASS_NAME,"GXPEntry")
    all_div_list.extend(entries)
