css或xpath selector：具有任何具有特定值的属性的元素 [英] css or xpath selector: elements which have any attribute with specific value

问题描述

我想匹配HTML Dom树中所有具有值foo的属性的元素。它应该是一个CSS或一个XPath选择器。

I want to match all elements in an HTML Dom tree which have any attribute with the value "foo". It should either be a CSS or a XPath selector.

我的天真的方法会像这样css选择器：

My naive approach would be something like this as css selector:

*[*='foo']

是正确的语法？

推荐答案

CSS没有定义一个以通配符作为其名称的属性选择器。

CSS does not define an attribute selector that takes a wildcard as its name.

XPath，但是。以下表达式应该可以工作：

XPath, however, does. The following expression should work:

//*[@*="foo"]
