我正在firefox中开发selenium python。我试图通过css选择器查找元素
element = "span:contains('Control panel')"
my_driver.find_element_by_css_selector(element)
我正处于错误之下
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidSelectorException: Message: Given css selector expression "span:contains('Control panel')" is invalid: InvalidSelectorError: 'span:contains('Control panel')' is not a valid selector: "span:contains('Control panel')"
在selenium IDE中,我可以通过这个字段成功地找到元素,但是在Python中它不起作用
