Overview

‘DOMParser` — public-facing parser entry point. Parses an HTML or XML string into a fresh `Dommy::Document`. Per spec, JS code often does:

const doc = new DOMParser().parseFromString(html, "text/html");

Supported mime types:

- `text/html`            (full HTML page)
- `application/xhtml+xml`/`application/xml`/`text/xml`/`image/svg+xml`
  all delegate to Nokogiri's XML parser

The returned Document has no ‘defaultView` (not attached to a Window). Useful for fragment parsing where you want a Document without spinning up a Window.
