我正在尝试使用Xpath或其他任何东西来定位元素<span _ngcontent-c19=""> ACME Nursing </span>
我已经尝试了多种使用动作来移动moveToElement的方法，以及许多其他方法，但是我只是无法进行悬停和点击。我也尝试过等待。无论我如何尝试，都会出现以下错误：
下面列出的是包含我要查找的隐藏元素的代码：

答案 0 :(得分：1)
选择器.//span[starts-with(@id,'ACME Nursing')]中没有元素。
您要获取包含ACME Nursing文本的元素，并且选择器的元素是//span[normalize-space(.)='ACME Nursing']，其中.是文本，而normalize-space则删除空格。
或者：//span[normalize-space(.)='ACME Nursing' and @_ngcontent-c19]
