 Starting with v0.4, all selection methods consistently return [Selector](#selector)/[Selectors](#selectors) objects, even for text nodes and attribute values. Text nodes (selected via `::text`, `/text()`, `::attr()`, `/@attr`) are wrapped in [Selector](#selector) objects. These text node selectors have `tag` set to `"#text"`, and their `text` property returns the text value. You can still access the text value directly, and all other properties return empty/default values gracefully.

->>> page.css('a::text')              # -> Selectors (of text node Selectors)
->>> page.xpath('//a/text()')         # -> Selectors
