php DOMDocument How to convert node value to string

PHP + DOMDocument: outerHTML for element?

I am trying to extract all img tags from a string. I am using:

$domimg = new DOMDocument();
@$domimg->loadHTML($body);
$images_all = $domimg->getElementsByTagName('img');

foreach ($images_all as $image) {
  // do something
}

I want to put the src= values or even the complete img tags into an array or string.

Solution

Use saveXML() or saveHTML() on each node to add it to an array:

$img_links = array();
$domimg = new DOMDocument();
$domimg->loadHTML($body);
$images_all = $domimg->getElementsByTagName('img');

foreach ($images_all as $image) {
  // Append the XML or HTML of each to an array
  $img_links[] = $domimg->saveXML($image);
}

print_r($img_links);

Thanks @Michael. That was what I needed. I had tried saveXML but I was using it incorrectly.
