Use regular expression to find html tags with id attribute in html

For example:
String

123213

21314423

Does not match the content of

...

To write this example, you can use
<[a-zA-Z0-9][^> ]+?id=[^>]+?>.*?

Match

Previous php example:

<?php 
$str = &#39;<div style="float:left" id="ab">123213</div><div class="a123">213123</div>&#39;; 
$search = &#39;#<[a-zA-Z0-9][^>]+?id=[^>]+?>.*?</div>#is&#39;; 
preg_match_all($search,$str,$r); 
echo &#39;<pre class="brush:php;toolbar:false">&#39;; 
print_r($r); 
echo &#39;

'; ?>

This example output

Array 
( 
[0] => Array 
( 
[0] => <div style="float:left" id="ab">123213</div> 
) 
)
