why don't you use the css to locate the element find_element_by_css_selector("span.layui-layer-setwin>a") – Alex Bruce
How do you want to handle pseudo element? What is desired output? – Andersson
it is auto test script like below: click element "span.layui-layer-setwin>a" – Diese Xu
@Alex Bruce , I am tyring – Diese Xu
@DieseXu, if you want to click, then you need <a> element. ::before is not a part of DOM, so you cannot locate and click it – Andersson

Pseudo web elements wont be part of DOM so it is not possible to get attribute value from selenium2library. Instead we can get it from Execute Javascript like below snippet.

${attribute_value}=    Execute Javascript    return window.getComputedStyle(${element},${pseudo_element}).getPropertyValue('${attribute}');

I was looking for same and found great working code in below link. (JFI - No promo)

Check key "Get Pseudo Element CSS Attribute Value" in the below link.
