I have duplicate child elements in my RSS feed. Won't parse it in JavaScript

I'm pulling RSS data from this URL and this is how their data structure looks like.

<item>
<itunes:episodeType>full</itunes:episodeType>
<itunes:season>6</itunes:season>
<itunes:episode>49</itunes:episode>
<itunes:season>6</itunes:season>
</item>

It has duplicate child element itunes:season. How do I correctly parse it in JavaSCript? Any help will be apprciated! :)

here is the gist of my code:

        success: function(data) {
          
             .find("item")
             .each(function() {
              const el = $(this);

               const seasonLS = el.find("itunes\\:season").text();
               const episodeLS = el.find("itunes\\:episode").text();
          
    };

I tried fetching it by the childname but the duplicate childnames are throwing it off.

Edit:

Sorry for the unclear question. Here is more information.

1. The expected output for itunes:season is 6. This one spits out 66.

2. .find is chained on below:

const RSS_URL = *** URL ***;

    $.ajax(RSS_URL, {
        accepts: {
            xml: "application/rss+xml"
        },

        dataType: "xml",

        success: function(data) {
            console.log(data)

$(data) .find("item")...
