PHP Remove all hyperlinks of specific domain and subdomain

I am trying to Remove all hyper links of specific domain and sub domain from text..
Here is what I am trying

$link = '<a href="http://www.my.com/app/319354212" class="hh"> with www </a> 
        example <a href="http://my.com/app/319354212" class="hh"> No www </a>
        <a href="http://www.subdomain.my.com/app/319354212" class="hh"> Subdomain</a>
        <a href="http://www.yahoo.com/app/319354212" class="hh"> yahoo</a> ';
$pattern1 = '|<a [^>]*href="http://www.my.com(.*)">(.*)</a>|iU';
$str = preg_replace($pattern1, "\\2", $link);
 echo $str

Ok I just want to remove all domains+subdomains for my.com but yahoo.com should not be removed.
I am getting output of only 1st link removed rest all there

<?php
$link = '<a href="http://www.my.com/app/319354212" class="hh"> with www </a> 
    example <a href="http://my.com/app/319354212" class="hh"> No www </a>
    <a href="http://www.subdomain.my.com/app/319354212" class="hh"> Subdomain</a>
    <a href="http://www.yahoo.com/app/319354212" class="hh"> yahoo</a> ';
$pattern1 = '~([<]a\s+href="http\:\/\/)([a-zA-Z0-9]+\.)*(my\.com)([^>]*["][>])(.*)(</a>)~i';
// I'm not sure if you want to keep the text or not, but if you do not
// want to keep it, remove $3 from the next line (so it's now '' instead):
$replacement = '$3';
$str = preg_replace($pattern1, $replacement, $link);
echo $str;

This does a small job:

<?php
$link = '<a href="http://www.my.com/app/319354212" class="hh"> with www </a> 
        example <a href="http://my.com/app/319354212" class="hh"> No www </a>
        <a href="http://www.subdomain.my.com/app/319354212" class="hh"> Subdomain</a>
        <a href="http://www.yahoo.com/app/319354212" class="hh"> yahoo</a> ';
$pattern1 = '|<a href="http://(www\..*)?my.com(.*)">(.*)</a>|iU';
$str = preg_replace($pattern1, "\\3", $link);

echo "<textarea style=\"width:700px; height:90px;\">"
  . $str
  . "</textarea>";
?>

Gives:

with www  
    example  No www 
     Subdomain
    <a href="http://www.yahoo.com/app/319354212" class="hh"> yahoo</a>
