Text and attribute pseudo-selectors

See original GitHub issue

Pre W3C, CSS Selectors only select nodes within XML documents, however they do not select text nodes or attribute values. Frameworks like parsel (scrapy) have successfully implemented pseudo-selectors like ::text or ::attr which allow you to do that.

Given soupsieve’s current architecture, is it possible to add such selectors?

While it is certainly possible to implement this. I think I’m going to pass. It adds unnecessary complexity and inefficiency for very little gain. I’m yet to hear how this is more helpful than just calling text on the returned elements.

While I’m open to a conversation on this, as things stand now, there are no plans to implement these.

Currently, I have intentionally not implemented any pseudo elements, just pseudo classes. Beautiful soup can access such on the returned element.

Given soupsieve’s current architecture, is it possible to add such selectors?

It is most likely possible, but I would need to decide whether that is a path that I want to go down. If I did go down this path, I would probably support no more than ::text and maybe ::attr.

This would of course add a bit more complexity as pseudo elements can’t be processed in certain cases etc.

I won’t say no, but I’ll leave it as a maybe. If I do this, it may have to wait until I have the time to spend as this would be a fairly big addition.
