Need help with isLive

[harddrop]

Hi, I know how to show the XML file for my stream: http://xharddropx.channel-api.livest...2.0/livestatus .

I want my site to show Off Air in text when it's false and On Air when it's true, but I don't know how. Does anybody know the programming code I should put? Same with the amount of viewers.

If it helps, I transitioned from Ustream and this is what my code used to looked like:

<script type="text/javascript">
function set_status(status)
{
if (status == "offline")
{
document.getElementById("status").innerHTML = "<b>Live Stream: Off Air</b>";
}
else if (status == "live")
{
document.getElementById("status").innerHTML = "<b>Live Stream: On Air</b>";
}
else
{
document.getElementById("status").innerHTML = "<b>Live Stream: Error</b>";
}
}
</script>

<script type="text/javascript" src="http://api.ustream.tv/json/channel/hard-drop-tetris-channel/getValueOf/status?key=****&callback=set_status">
</script>

Also, I have a LiveStream API key now, but do I need one? Where do I put it?
