如何将CSS选择器与"not"一起使用在C#中? [英] How to use css selector with "not" in c#?

问题描述

我想通过CSS选择器查找元素，但是我想跳过其中的一些元素，我该怎么做?

I want to find elements by css selector, but I want to skip some of them, how can I do it?

driver.FindElements(By.CssSelector("a[href]")) 

但是我不需要带已注销和客户/合同的href

but I need not to take href that has logoff and client/contract in it

推荐答案

您可能不需要LINQ.您可以使用:not()伪类，为每个要排除的值使用一个伪类(请注意每个否定项中的*=；我假设此处与子字符串匹配):

You probably don't need LINQ for this. You can use the :not() pseudo-class, one for each value you want to exclude (note the *= in each negation; I'm assuming substring matches here):

driver.FindElements(By.CssSelector("a[href]:not([href*='logoff']):not([href*='client'])"))

一个例外是，如果您有一个要排除的值的动态列表:您可以使用string.Join()或循环以编程方式构建选择器，然后将其传递给By.CssSelector()，或者可以遵循Richard Schneider的回答使用LINQ保持事物清洁.

An exception is if you have a dynamic list of values that you want to exclude: you can either build your selector programmatically using string.Join() or a loop and then pass it to By.CssSelector(), or you can follow Richard Schneider's answer using LINQ to keep things clean.
