Replace image scr with it's surrounding href

Question

I'm trying to add a filter to the content to replace the src of all images in the content with it's surrounding href link. Any ideas how to go about this?

The only thread I could find that came close was this: Replace image attributes for lazyload plugin (data-src)

Use this for example in the loop

$new_url = '<img src="http://www.google.nl';
$content = apply_filters('the_content', get_the_content());
$content = preg_replace("/(<img[^>]*src *= *[\"']?)([^\"']*)/i", $new_url,  $content);
