web scrape using preg_match_all

Question

I'm trying to get the contact information from this site http://www.internic.net/registrars/registrar-967.html using PHP.. I was able to get the e-email ad by using the href links by doing this:

$contactStr = "http://www.internic.net/registrars/registrar-967.html";
                $contact_string = file_get_contents("$contactStr");
                preg_match_all('/<a href="(.*)">(.*)<\/a>/i', $contact_string, $contactInfo);
                $email = str_replace("mailto:", "", $contactInfo[1][6]);

However, I'm having a hard time getting the address and the phone # since there's no html element I can use like < p > maybe.. I just need 1800 SW First Ave., Suite 440 Portland OR 97201 United States and 310-467-2549 from this site.. Please enlighten me on how to do this using preg_match_all or some other ways possible.. Thanks!

Have a look at [DOMDocument](http://www.php.net/domdocument). — Ja͢ck, Jan 15 '13 at 01:47
It is obligatory to also reference http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 surely the best answer of all time. — Devin Ceartas, Jan 15 '13 at 02:36
**Don't use regular expressions to parse HTML**. You cannot reliably parse HTML with regular expressions. As soon as the HTML changes from your expectations, your code will be broken. See http://htmlparsing.com/php.html for examples of how to properly parse HTML with PHP modules. — Andy Lester, Jan 15 '13 at 06:16

Instead of using regex try DOMDocument as others have said in comment.

Here is an example (bit hacky tho) hope it helps:

function get_register_by_id($id){
    $site = file_get_contents('http://www.internic.net/registrars/registrar-'.$id.'.html');
    $dom = new DOMDocument();
    @$dom->loadHTML($site);
    $result = array();
    foreach($dom->getElementsByTagName('td') as $td) {
        if($td->getAttribute('width')=='420'){
            $innerHTML= '';
            $children = $td->childNodes;
            foreach ($children as $child) {
                $innerHTML .= trim($child->ownerDocument->saveXML($child));
            }
            $fixed = array_map('strip_tags', array_map('trim', explode("<br/>",trim($innerHTML))));
            foreach($fixed as $val){
                if(empty($val)){continue;}

                $result[] = str_replace(array('! '),'',$val);
            }
        }
    }
    return $result;
}


print_r(get_register_by_id(965));
/*Array

    [0] => Domain Central Australia Pty Ltd.
    [1] => Level 27

print_r(get_register_by_id(966));
/*

print_r(get_register_by_id(967));
