Are you sure that the default php version on the server is php-7.1.x? do a rpm -qa | grep php and see what packages are installed. Also check /etc/php.d/, see if there is any .ini file that is supposed to load the xml php extesion/module.

You could also issue a php -i and then check for xml or create a info.php file with this content <?php phpinfo(); ?>. Place somewhere like in /var/www/html or wherever your apache root folder is and try accessing it in a web browser and check the php info output there and see if xml extension is actually loaded.
