Hello,

How can I find the class name that matches?  In the example below, I get additional class names.  I only want the alert to contain class names that have "hello" in them.

Instead of:
adsfd helloABC xyz adfdsfdasfadsf

The alert should be:
helloABC

// Thanks, leakim971
$(document).ready(function() {
 $('.xyz[class*="hello"]').each(function(index) {
  alert('The matching class is: ' + $(this).attr('class'));
 });
});

</script>
</head>

<h1 class="adsfd helloABC xyz adfdsfdasfadsf">Heading</h1>
<div class="hello1">1</div>
<div class="adsfdsf hello123 dasfads fdsa sd adsf xyz">2</div>
<div class="hello3">3</div>
<p class="nomatch  xyz">This should not be included</p>
<p class="helloP">ABC</p>
<p class="helloTest cvsdfadfasf xyz">XYZ</p>
