     * Here you can use standard WordPress functions like get_post_meta() and get_post() to
     * retrieve data, make changes and then save them with update_post() and/or update_post_meta()
     *
     * There are two ways to access the data from the current record in your import file:
     *
     * 1) Custom fields. For example, you could import a value to a custom field called "_temp" and
     *  then retrieve it here. Since it's only temporary, you'd probably want to delete it immediately:
     *
     *     $my_value = get_post_meta($post_id, "_temp", true);
     *     delete_post_meta($post_id,"_temp");
     *
     * 2) The $xml param (a SimpleXMLElement object). This can be complex to work with if you're not
     * used to iterators and/or xpath syntax. It's usually easiest to convert it a nested array using:
     *
     *     $record = json_decode(json_encode((array) $xml_node), 1);
