Use PHP to find text within an HTML Page

Question

I would like to write some PHP code to parse some HTML to return the href and title of all of the images in the "image_url" a class. I am currently using substr to find the location of the strings, however the webpage sometimes changes content and I can't always rely on substr. Is there a DOM way or some other regular expression way I can find these elements within my HTML?

<a class="image_url" href="/123.jpg" target="_blank"><img src="/123.jpg" border="0" title="Some dynamic length image title that is making this difficult for me"></a>

Something like `$sreg = '|]*href="([^"]*)"[^<]+]*title="([^"]*)"|i'; preg_match_all($sreg, $sText, $a);` — Victor, Apr 05 '13 at 07:23

You can try below sample code.

$html='<a class="image_url" href="/123.jpg" target="_blank"><img src="/123.jpg" border="0" title="Some dynamic length image title that is making this difficult for me"></a>';   
 $dom = new DOMDocument();
    $dom->loadHTML($html);

    $elements = $dom->getElementsByTagName('a');
    foreach ($elements as $child) {
        echo $child->nodeValue;
    }
