Here is modified code if you do not want to worry about the order of the photos being sideloaded needing to match the order in which they appear in the content and also matching the sizes.

`
public function action_pmxi_saved_post($id) {
$media = get_attached_media( 'image', $id );

$img_array = [];
$dir = wp_upload_dir();
foreach($media as $media_id => $item) {
$metadata = wp_get_attachment_metadata($item->ID, true);
$directory = explode('/', $metadata['file']);
$metadata['directory'] = "{$directory[0]}/{$directory[1]}";

foreach ($metadata['sizes'] as $size => $args) {
  $img_array[$args['file']] = array('id' => $media_id, 'url' => "{$dir['baseurl']}/{$metadata['directory']}/{$args['file']}");
}

}
$thepost = get_post($id);
remove_all_filters('the_content');
$html = $thepost->post_content;
$doc = new DOMDocument();
@$doc->loadHTML( $html );
$imageTags = $doc->getElementsByTagName( 'img' );
$i = 0;

foreach( $imageTags as $tag ) {
$tag_url = $tag->getAttribute('src');
$classes = $tag->getAttribute('class');

foreach ($img_array as $filename => $args) {
  if ( strpos($tag_url, $filename) ) {
    $classes_new = preg_replace('/wp-image-[0-9]*/i', "wp-image-{$args['id']}", $classes);
    $tag->setAttribute('class', $classes_new);
    $tag->setAttribute('src', $args['url']);
    continue;
  }
}

}
$newhtml = preg_replace(array('/<!DOCTYPE.*\n?

/', '/</p></body></html>/'), '', $doc->saveHTML());
$args = array(
'ID' => $id,
'post_content' => $newhtml,
);
wp_update_post( $args );
}
