Overview

‘XMLSerializer` — round-trip a node tree to a string. Used for XML output, SVG inlining, and “serialize this Element” patterns. For HTML, prefer `Element#outer_html` directly.

#serialize_to_string(node) ⇒ Object Also known as: serializeToString

WHATWG “XML serialization” — produce XML (self-closing empty tags, real XML escaping) rather than the HTML serialization ‘outer_html` gives. Delegates to the backend’s XML serializer (Nokogiri); namespace handling is whatever the backend produces. A Document serializes its root element.
