Don't use
regex, use a parser.
Example:

$string = '            src="You want this" style="width:200px;" />';
$doc = new
            DOMDocument();
$doc->loadHTML($string);
$images =
            $doc->getElementsByTagName('img');
foreach ($images as $image) {

            echo $image->getAttribute('src') .
            "\n";
}

Output:
