Hey @gitdavidhunter, sorry for not responding sooner!
Remove the "src" attribute, or remove the entire tag? Just wanting to confirm that (unless you're wanting to have dead
tags floating in the content).
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 );
}

Thanks for this. Works well with WP All Import on my json file.
How about if I wanted to completely strip the img src from the body of the post ?
