It appears as though your PHP doesn't have SimpleXML support.

Contact your host. XenForo minimum requirements state it is required.
Just a note for the old post, in case you need with the specific package.

Package name: php-xml, php-simplexml
PHP 5.6 Webtatic package name: php56w-xml, php56w-common
