# AssertHTML

AssertHTML is an Elixir library for parsing and extracting data from HTML and XML with CSS.


## Usage
```elixir
defmodule ExampleControllerTest do
  use ExUnit.Case, async: true
  use AssertHTML

  test "shows search form", %{conn: conn} do
    conn_resp = get(conn, Routes.page_path(conn, :new))
    assert response = html_response(conn_resp, 200)

    response
    |> assert_html_selector("p.description")
    |> refute_html_selector(".flash-message")
    |> assert_html_attributes("form.new_page", [action: Routes.page_path(conn, :create), method: "post"], fn(html)->
      html
      |> assert_html_attributes("label", class: "form-label", text: "Page name")
      |> assert_html_attributes("input", type: "text", class: "form-control", value: "", name: "page_name")
      |> assert_html_attributes("button", class: "form-button", text: "Submit")
    end)
  end
end
