I've found an error on a page in my Magento application; it always show this message error when I visit it:

Fatal error: Class 'DOMDocument' not found in /home/.../lib/Zend/Feed/Abstract.php on line 95

Can you give me a solution? I'm using magento 1.4.1.1.

You need to install the DOM extension. You can do so on Debian / Ubuntu using:

sudo apt-get install php-dom

And on Centos / Fedora / Red Hat:

yum install php-xml

If you get conflicts between PHP packages, you could try to see if the specific PHP version package exists instead: e.g. php53-xml if your system runs PHP5.3.

I'm using CentOS 7 with virtualmin and three PHP versions. I also have REMI repo enabled. it worked for me:

Step 1:

Just append PHP major version number like this php{version number}-xml. And run yum install

yum install php70-php-xml
yum install php71-php-xml
yum install php72-php-xml

Step 2:

Don't forget to restart Apache:

service httpd restart

If compiling from source with --disable-all then DOMDocument support can be enabled with
--enable-dom

Example:

./configure --disable-all --enable-dom

Tested and working for Centos7 and PHP7

For PHP 7.4 Install the DOM extension.

Debian / Ubuntu:

sudo apt-get update
sudo apt-get install php7.4-xml
sudo service apache2 restart

Centos / Fedora / Red Hat:

yum update
yum install php74w-xml
systemctl restart httpd

For previous PHP releases, replace with your version.

In my case the problem was it was the use of namespace at the top of php file, exemple :

namespace MediaWiki\Extensions\ParserFunctions;

To solve this problem add the following line:

use DOMDocument;

So no need of installing dom or xml if they are already installed. It is a php language trap.

Package php-dom is a virtual package provided by:
  php7.1-xml 7.1.3+-3+deb.sury.org~xenial+1
  php7.0-xml 7.0.17-3+deb.sury.org~xenial+1
  php5.6-xml 5.6.30-9+deb.sury.org~xenial+1
You should explicitly select one to install.

In case anyone using 5.6 versions then go with this way

sudo apt-get install php5.6-xml

For PHP ver PHP7, Ubuntu:

sudo apt-get install php7.1-xml

or by

yum install php-xml

PHP8: (latest version)

sudo apt-get install php8.0-xml

PHP7:

You can also do:

and apt-get will show you where it is.

After a long time suffering from it in PHPunit...

For those using namespace, which is very common with Frameworks or CMS, a good check in addition to seeing if php-xml is installed and active, is to remember to declare the DOMDocument after the namespace:

namespace YourNameSpace\YourNameSpace;

use DOMDocument; //<--- here, check this!

If you are using PHP7.0 to install Magento, I suggest to install all extensions by this command

sudo apt-get install php7.0 php7.0-xml php7.0-mcrypt php7.0-curl php7.0-cli php7.0-mysql php7.0-gd libapache2-mod-php7.0 php7.0-intl php7.0-soap php7.0-zip php7.0-bcmath

I need to Google some times to meet Magento requirement.

I think you can replace the PHP version to 7.x if you use another PHP version

And restart Apache is needed to load new extensions

sudo service apache2 restart

Create an empty PHP file and put only <?php phpinfo(); in it, look at it in a browser.
Check if you can spot --disable-dom in the configuration options and/or if you can see details about the DOM extension in the list below.

If you cannot see DOM in the list or you see it is disabled, your PHP installation does not include the DOM extension. You'll need to recompile your PHP installation from source to remedy that.
