Help please - using xml info to display image

[xDISTURBDx]

This is my first time attempting PHP coding and I cant seem to figure it out exactly, so any help is very much appreciated.

Just in case I made a huge mess of this, its supposed to be looking into the xml file and check the viewer count. If VC is 0 then display an offline image if VC is anything else then display online image.

The only thing I get on a webpage is viewers_count!=0){ echo ''; }else{ echo ''; } ?>

[php]

<?php $xml = simplexml_load_file("http://api.justin.tv/api/stream/summary.xml?channel=halucen"); if($xml->viewers_count!=0){ echo ''; }else{ echo ''; } ?>

[/php]

give this a shot:

<?php
$xml = simplexml_load_file("http://api.justin.tv/api/stream/summary.xml?channel=halucen");
if($xml->viewers_count[0]==0){
echo '<img src="http://myimglink.com/img.png" border=0>';
}else{
echo 'bob';
}
?>
