Solution 3:

<body><scripttype="text/javascript">window.onload = function () {
            var outputSpan = document.getElementById('outputSpan'),
                iFrame = frames['subjectIFrame'];

            iFrame.document.location.href = 'http://live.xbox.com/en-US/friendcenter/RecentPlayers?Length=1';
            (function () {
                var nodes = iFrame.document.getElementsByTagName('dd'),
                a = [];
                for (var i in nodes) if (nodes[i].id) {
                    (nodes[i].id.match(/fc\-gtag\-/)) && (a.push(nodes[i].id.split('-')[2]));
                }
                for (var j in a) if (a.hasOwnProperty(j)) {
                    outputSpan.innerHTML += (a[j] + '<br />');
                }
            })();
        };
    </script><spanid="outputSpan"></span><iframeid="subjectIFrame"frameborder="0"height="100"width="100" /></body>

Solution 4:

What does "I can't seem to use document.getElementsByID correctly in this instance" mean? Are you referring to the fact that you are misspelling getElementByID?

Solution 5:

So...something like this (jQuery)?

var els = [];

$('.fc-content-panel.fc-friend').each(function() {
  els.push(this));
});

Now you have an array of all the elements that have both of those classes.
