Decode a part of a website

Hi everyone. I am very new to elixir but finding it amazing. Here is what I am trying to do. I am trying to decode a certain part of a website that contains aviation forecast (Called TAF). In my mix.exs I have added the tesla and poison deps. I am using the steps from this site (https://medium.com/the-wheel/writing-your-first-elixir-package-part-2-4bd689a8551a).

The aviation weather site is (https://metarreader.com/FACT). FACT is the code for Cape Town. If you inspect the code (I am using google), you will find: section class=“report” . That will show you the weather forecase.

What I have done (Working in iex) is:

1. response = Tesla.get(“https://metarreader.com/FACT”) All OK so far
2. response = response.body. All OK so far
3. {:ok, result} = Poison.decode response . This is where I get the following error:

** (MatchError) no match of right hand side value: {:error, {:invalid, “<”, 0}}

The way I see it is that I am trying to decode the entire body and there are many HTML tags which I understand. What I am trying to do as mentioned, is just get that part of the site that shows the forecast.

Kind regards
Dmitri
