Yesod.Test.TransversingCSS
This module uses HXT to transverse an HTML document using CSS selectors.
The most important function here is findBySelector, it takes a CSS query and a string containing the HTML to look into, and it returns a list of the HTML fragments that matched the given query.
Only a subset of the CSS spec is currently supported:
By tag name: table td a
By class names: .container .content
By Id: #oneId
By attribute: [hasIt], [exact=match], [contains*=text], [starts^=with], [ends$=with]
Union: a, span, p
Immediate children: div > p
Get jiggy with it: div[data-attr=yeah] > .mon, .foo.bar div, #oneThing
