Hello I am implementing a scraper which scrape the latest message received in a telegram public channel. This is how the html is 
I can fetch all the divs under section class tgme_channel_history. It has five divs under it which means five different messages. I want to get only the last div. How can I do that.
You can check the live HTML here https://telegram.me/s/newlink01/
const $ = require('cheerio');
const url = 'https://telegram.me/s/newlink01/';
rp(url)
.then(function (html) {
//success!
const wikiUrls = [];
$('.tgme_channel_history', html).each(function () {
wikiUrls.push($(this).text()
});
console.log(wikiUrls[0]);
})
.catch(function (err) {
//handle error
});
