如何从<ri：attachment ri：filename =“stories-img-05.png”/>中提取图像路径

Here is the original code where I am extracted the data using Simple HTML Dom:

<div class="content-wrapper"><p><ac:image ac:height="250"><ri:attachment ri:filename="stories-img-05.png" /></ac:image></p></div>

Here is the code which i am using :

$html->find('div[class=content-wrapper] p ac:image ', 0)->innertext;

How can I get Image Path?

For multiple use this code:

    $img=array();
    foreach($html->find('div.content-wrapper ri:attachment[ri:filename]') as $article) {
        array_push($img, $article->attr['ri:filename']);
    }
    print_r($img);

For single use this:

$html->find('div.content-wrapper ri:attachment[ri:filename]')[0]->attr['ri:filename']
