How do I get a specific elements value that has no unique identifiers with Cheerio

Question

I'm trying to get a specific elements value with Cheerio however I'm unsure how. I've looked over the documentation and so far, no dice.

Website example of the value I'm trying to get, specifically the <dd> that holds the number value of player count.

const URL = 'https://www.battlemetrics.com/servers/dayz/16108490';
axios(URL)
.then(response => {
    const html = response.data
    const $ = cheerio.load(html)
    const players = []
    $('.server-info', html).each(function() {
        const scrape_test = $(this).text()
        const pNum = $(this).find('dd').val()
        players.push({
            scrape_test,
            pNum
        })
    })
    console.log(players)
}).catch(err => console.log(err))

scrape_test is just ensuring that I'm actually receiving data and it does indeed grab the data including the value I need however I don't know how to refine it to grab specifically what I need.

The response from pNum is undefined, I've tried removing .val() in which I then receive 6 array elements however when I try to iterate over them to push them out, I then get another undefined. If I pick a specific position I equally get an undefined.

For the player count value, you can filter <dt> elements by their text contents, then pull the next element to find the corresponding <dd>:

const $ = cheerio.load(html);
const dt = [...$("dt")]
  .find(e => $(e).text().trim().toLowerCase() === "player count");
console.log($(dt).next().text()); // => 7/65

Another option is the :contains() pseudoselector and the adjacent sibling combinator:

const text = $('dt:contains("Player count") + dd').text();
