Thanks, but it does not work for me.  Please test this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Demo</title>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script type="text/javascript">

$(document).ready(function() {
 $('[className^="hello"]').each(function(index) {
  alert($(this).attr('class'));
 });
});

</script>
</head>
<body>

<h1 class="helloH">Heading</h1>
<div class="hello1">1</div>
<div class="hello2">2</div>
<div class="hello3">3</div>
<p class="nomatch">This should not be included</p>
<p class="helloP">ABC</p>
<p class="helloXYZ">XYZ</p>

</body>
</html>

Sorry for the delay I was very busy...
replace className by class :

So use : $('[class^="hello"]')
or : $('*[class^="hello"]')
Test page :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Demo</title>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script type="text/javascript">

$(document).ready(function() {
 $('[class^="hello"]').each(function(index) {
  alert($(this).attr('class'));
 });
});

</script>
</head>
<body>

<h1 class="helloH">Heading</h1>
<div class="hello1">1</div>
<div class="hello2">2</div>
<div class="hello3">3</div>
<p class="nomatch">This should not be included</p>
<p class="helloP">ABC</p>
<p class="helloXYZ">XYZ</p>

</body>
</html>
