how to install XMLWriter PHP modules

Posted on October 3, 2016

when i installed wp all import plugin, it gave me this error: " Required PHP components are missing.

WP All Import requires DOMDocument, XMLReader, and XMLWriter PHP modules to be installed. These are standard features of PHP, and are necessary for WP All Import to read the files you are trying to import. Please contact your web hosting provider and ask them to install and activate the DOMDocument, XMLReader, and XMLWriter PHP modules."

Hello, all

In order to install XMLWriter on Ubuntu use:

sudo apt-get install php-xml

and then restart your web server (Apache/Nginx)

If you want to install it for specific PHP version you can use this command:

sudo apt-get install php7.3-xml

and then again restart your web server.

For CentOS:

yum install libxml2

yum install php-xmlwriter

yum install php-xml

Once this is done you’ll need to restart the web server.

You can also check with a phpinfo file if the extension is enabled or use the following command in your terminal:

php -i | grep xmlwriter

The output should be:

root@digitalocean:~# php -i | grep xmlwriter
/etc/php/7.2/cli/conf.d/20-xmlwriter.ini,
xmlwriter

Hope that this helps! Regards, Alex

These modules are packaged separately by Ubuntu (assuming that you are using Ubuntu).

The following should resolve the problem:

Ubuntu 14.04

sudo apt-get update 
sudo apt-get install php5-xml

Ubuntu 16.04

sudo apt-get update 
sudo apt-get install php7.0-xml
