title: NodeJS Cheerio Scraping li tags always returns NULL
body: <p>I'm trying to zero in on the URL contained within the li tags on the page in my URL variable. It should be simple, but I can't get it to work. I get the correct number of elements, but they are all blank. text() returns '' &amp; html() returns null. What am I doing wrong here?</p>
  
  <pre><code>const cheerio = require('cheerio');
  const request = require('request');
  
  function getHistory(){
    let url = 'http://coinmarketcap.com/historical/';
    request(url,(error,response,html)=&gt;{
      var $ = cheerio.load(html);
      $('li.text-center').each((i,element)=&gt;{
        var omg = $(this).html();
        console.log(omg);
      });
    });
  }
  </code></pre>
