Question

我对selenium python真的很陌生，并坚持一个我无法弄清楚的问题。请有人帮忙。我想要定位此按钮并单击它，但问题是页面上还有其他按钮具有完全相同的类ID等，这两个按钮之间只有1个区别。

aria-label=""

我要点击的aria-label内的文字以

开头

dislike this video

文本是动态的，但起点只是下面描述的数字更改相同。我只想定位此按钮并单击它，因为两个按钮具有完全相同的类，所以我觉得只有这个标记可以被定位和点击。我可以告诉我如何定位起始文本甚至（不喜欢）会起作用。然后单击按钮。下面是按钮代码。

<button is="paper-icon-button-light" id="button" class="style-scope ytd-toggle-button-renderer style-text" aria-label="dislike this video along with 14,279 other people" aria-pressed="false">

我尝试了这段代码，但只有在文字完全匹配时才能正常工作

driver.find_element_by_css_selector('button[aria-label="dislike this video along with 14,279 other people"]').click()

所以上面标签中的数字会发生变化，但它不起作用。

简单来说，有2个按钮具有完全相同的类等，但我想点击第二个按钮。如何用selenium python做到这一点？

Answer 1

您尝试使用以下css -

driver.find_element_by_css_selector('button[aria-label^="dislike this video"]').click()

或使用xpath -

 driver.find_element_by_xpath('//button[starts-with(@aria-label,"dislike this video")]').click()

Answer 2

尝试以下xpath -

(//*[@id="button"]/yt-icon)[2]
