There are a handful of places where we don't check that the XML functions exist before we use them. Ubuntu's PHP 7 packages don't include PHP-XML by default, increasing the chance of this causing issues. Props kraftbj, markoheijnen. Fixes #37122. Built from https://develop.svn.wordpress.org/trunk@38883 git-svn-id: http://core.svn.wordpress.org/trunk@38826 1a063a9b-81f0-0310-95a4-ce76da25c4cd
