Hello,
Create xstore-child/woocommerce/loop/result-count.php file with the necessary code. Keep the original parent theme file. Don’t change anything in the parent theme. Read more about child themes https://developer.wordpress.org/themes/advanced-topics/child-themes/ Besides, we are not responsible for users’ customization. Customization service is outside the scope of our support https://themeforest.net/page/item_support_policy
