# `Coelho.HTML`
[🔗](https://github.com/nseaSeb/coelho/blob/main/lib/coelho/html.ex#L1)
Importing existing HTML into a document.
This is the migration path. An application that already stores rich text as
HTML — in a `:string` column, from another editor, from a feed — has to get

it:
{:ok, document, _warnings} = Coelho.HTML.from_html(post.body_html)
post
|> Ecto.Changeset.change(%{body: document})
|> Repo.update()
Requires [Floki](https://hex.pm/packages/floki), declared as an optional
dependency: the parser is only needed on this path, and the document core
has no dependencies at all.

* an element the schema has no rule for is **transparent** — it
disappears and its children take its place, so a `` wrapper or a
`` does not cost you the text inside it
* `
