Я пытаюсь получить доступ к значению 12345 из элемента span на целевой веб-странице, который выглядит следующим образом:
<span id="[long-dynamically-generated-unique-id]:StaticFixedString"> 12345</span>
[long-dynamically-generated-unique-id] - это уникальный идентификатор, который изменяется каждый раз, когда я посещаю веб-сайт.Поэтому я хочу основать свой селектор на :StaticFixedString.Я могу сделать это следующим образом:
amt = driver.find_element_by_xpath(u"//*[contains(@id, 'StaticFixedString')]")
По крайней мере, в режиме отладки я могу видеть amt в окне переменных PyCharm следующим образом:
Когда я щелкаю треугольную стрелку перед переменной, чтобы раскрыть ее свойства, значок панели задач окна Chrome, открытого селеном, начинает мигать.Переменное окно PyCharm показывает Collecting data... следующим образом:
Через некоторое время оно показывает что-то вроде этого:
Затем регистрируется следующая ошибка:

Почему это происходит?Чего мне не хватает?

Для целевого размера отключен щелчок правой кнопкой мыши.Может ли это быть проблемой?
