Hi,

I'm sorry. I didn't read your request properly. Below you'll have a 
correct solution:

<?php

$html = <<<END_OF_HTML

<b>hello</b>
<b class="blah">hello</b>
<p>hello</p>
<p class="blah">hello</p>
<a>hello</a>
<a href="url">this</a>
<a>hello</a>
<a href="regex yo">hello</a>
<a>hello</a>
<a id="2" href="regex yo">hello</a>
<p>that</p>
<p class="blah" title="whatever">hello</p>
END_OF_HTML;

$tags = array();
$tags[] = 'p';
$tags[] = 'a';

$attr = array();
$attr[] = 'class';
$attr[] = 'href';

$vals = array();
$vals[] = 'blah';
$vals[] = 'url';
$vals[] = 'yo';

$text = array();
$text[] = 'hello';
$text[] = 'this';
$text[] = 'that';

$tags = implode('|', $tags);
$attr = implode('|', $attr);
$vals = implode('|', $vals);
$text = implode('|', $text);

$pattern = 
'/<('.$tags.')[^>]*('.$attr.')[^>]*('.$vals.')[^>]*>('.$text.')[^<\/]*<\/\1>/i';

echo $pattern."\n";
echo "--------------------\n";

preg_match_all($pattern, $html, $matches);

var_dump($matches);

?>
