You can't, generated pseudo-elements don't exist in the DOM (yet, sadly).

We can prove this like so:

CSS:

#foo:before {
  content: '[Before]'
}
#foo:after {
  content: '[After]'
}

HTML:

<body><div id="foo">Foo</div></body>

JavaScript:

(function() {

  var msgs = [];
  var child;
  var div;

  for (child = document.body.firstChild;
       child;
       child = child.nextSibling) {
    if (child.id) {
      msgs.push("Child " + child.nodeName + "#" + child.id);
    }
    else {
      msgs.push("Child " + child.nodeName);
    }
  }

  div = document.createElement('div');
  div.innerHTML = msgs.join("<br>");
  document.body.appendChild(div);

})();

The page resulting from the above (if we assume the script element is added to body at the end) is:

[Before]Foo[After]
Child DIV#foo
Child SCRIPT

As you can see, the generated pseudo-elements are just not present at all as far as the DOM is concerned.
