selenium.common.exceptions.InvalidSelectorException with “span:contains('string')" [英] selenium.common.exceptions.InvalidSelectorException with "span:contains('string')"

问题描述

我正在 Firefox 中研究 selenium python.我正在尝试通过 css 选择器查找元素

I am working on selenium python in firefox. I am trying to find element by css selector

element = "span:contains('Control panel')"
my_driver.find_element_by_css_selector(element)

我遇到了错误

 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，我可以通过该字段成功找到元素，但在 Python 中它不起作用

In selenium IDE I am successfully able to find element by this field but in Python it is not working

推荐答案

Selenium 不支持使用 css_selector 通过文本定位元素(尽管它可以在开发者工具控制台中使用).唯一的可能是 xpath

Using css_selector to locate element by text is not supported in Selenium (although it will work in the developer tools console). The only possibility is xpath

element = "//span[contains(text(), 'Control panel')]"
my_driver.find_element_by_xpath(element)

@FlorentB 的评论:

a comment by @FlorentB:

控制台也不支持 css 选择器，但 JQuery 支持.控制台中的 $('...') 是 document.querySelector 的简写，当页面有它时，它通常会被 JQuery 覆盖.

A css selector is not supported by the console either, but JQuery supports it. The $('...') from the console is a shorthand for document.querySelector which is generally overridden with JQuery when the page has it.
