Wordpress - wp_insert_post with resized post thumbnail in WordPress

I will crawl some data from an XML file and I have all the information I need including the image URL.

There is a function in WordPress called wp_insert_post which is used to create posts programmically. So far, so good. Simple to use:

What I also need is:

Add an image attached to the post thumbnail by its image URL (for example http://www.test.com/my-image.jpg)
Resize it on upload with WordPress built in functions (for example max 300 x 300, like medium thumbnail settings

You can use this function for that.

media_sideload_image($url,$post_id,$description);

There is a post about this here.

And in the theme you can use this function for getting the thumb in required size

<?php echo get_the_post_thumbnail( $id, $size, $attr ); ?>
