PHP DOMDocument missing

I am getting an odd error when running $dom = new DOMDocument("1.0", "utf-8");: Warning: require_once(classes/DOMDocument.class.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/html/cms/bootstrap.php on line 5

Fatal error: require_once() [function.require]: Failed opening required 'classes/DOMDocument.class.php' (include_path='.:/usr/share/pear:/usr/share/php:/var/www/html/cms/plugins/Zend/library') in /var/www/html/cms/bootstrap.php on line 5

According to php.net/manual/en/dom.setup.php, I need php-xml installed. I have tried this but it also errors out...

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

Fixed with:

sudo yum --enablerepo=webtatic install php-xml
sudo /sbin/service httpd stop
sudo /sbin/service httpd start

First Install this rpm

rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

Then install

sudo yum --enablerepo=webtatic install php-xml

This should 100% works.

I had same issue, I have php71 REMI installed on Centos7.

I checked this:

yum install php-xml

But It was installed and I got this message:

Package php-xml-7.1.4-1.el7.remi.x86_64 already installed and latest version

Then I tried this one:

yum install php71-php-xml

And It was missed, So I got
