Converting XML to JSON and output to HTML with jQuery

I'm trying to test out an idea I had but using this XML to JSON script: https://github.com/sergeyt/jQuery-xml2json

But then take the JSON data and then output that into HTML with jQuery.

So far, I've been able to load up the data correctly and I can console.log out the JSON data which turns out to be something like this:

releases:
  $: {}
  matching_count: "698"
  returned_count: "50"
  latestModified: "1537876805"
  release: Array(50)
   0:
    $: {}
    id: "713"
    headline: "Eiger BioPharmaceuticals to Participate in Investor Conferences"
    released: "1537876800"
    releaseDate: "Tue, 25 Sep 2018 08:00:00 -0400"
    modified: "1537876805"
    modifiedDate: "Tue, 25 Sep 2018 08:00:05 -0400"
  1:
   $: {}
    id: "712"
    headline: "Communications industry innovator to speak at AMEC Global Summit"
    released: "1491400800"
    releaseDate: "Wed, 05 Apr 2017 10:00:00 -0400"
    modified: "1491400806"
    modifiedDate: "Wed, 05 Apr 2017 10:00:06 -0400"
...

My JS code that I have so far is this:

var ul = $("<ul>").appendTo("body");
$.ajax({
  url: "https://s3-us-west-2.amazonaws.com/s.cdpn.io/8689/list.xml",
  dataType: "xml",
  success: function(response) {
    json = $.xml2json(response);
    console.log(json);
    $(json).each(function(index, headline) {
      ul.append($(document.createElement("li")).text(headline));
    });
  }
});

The issue is that when it renders out, all that comes back is [object Object] in a single li.

So, I know that I'm doing something incorrectly, but I'm not sure where and at what point I need to change over to get the data so I can render out the headline, releaseDate, and so on.

I've created a Codepen here: https://codepen.io/ultraloveninja/pen/YzPRjRw

I've read that I might need to use jQuery.parseJSON but after testing that a bit, I get some errors since it's still getting in that object.Object again.

I feel that I need to drill down a bit more to get within the releases.release somehow since that's where all the data is at to be rendered out.

The response you try to loop is an object representing the xml document. To access the releases array you have to use json["#document"].releases.release

var ul = $("<ul>").appendTo("body");
$.ajax({
  url: "https://s3-us-west-2.amazonaws.com/s.cdpn.io/8689/list.xml",
  dataType: "xml",
  success: function(response) {
    json = $.xml2json(response);
    let release = json["#document"].releases.release
    $(release).each(function(index, headline) {
      ul.append($(document.createElement("li")).text(headline.headline));
    });
  }
});
