如何在属性选择器中使用/模拟类似正则表达式的

How can I use/emulate regex-like backreferences in attribute selectors?(如何在属性选择器中使用/模拟类似正则表达式的反向引用?)

问题描述

我想要做的是在一个地方编写一个匹配任意值的选择器，然后需要一个不同的值等于它.如果 [attr="value"] 将value"解析为正则表达式，那么这将解决我的问题:

What I want to do is write a selector that matches an arbitrary value in one place, then later requires a different value be equal to it. If [attr="value"] parsed "value" as a regex, then this would solve my problem:

*[class="(.+)"] *[class="if_1"] {/* styles *
