Overview

Represents some HTML-esque styled text

The incredibly naive parser assumes all sorts of things about your notes, and faithfully turns them into a StyledText object.

Will probably crash horridly if you try something nasty on it. Don’t do that. Things it will choke on (off the top of my head):

  • Nested <run>s

  • <run>s with attributes

  • <text> or <note> tags within the body of this actual note

  • All kinds of other things?
