问题
I'm using XAMPP Server 1.7.7
While opening the php file, i receive the error
Fatal error: Class 'XSLTProcessor' not found
回答1:
Install the XSL extension to get that class. This might be as easy as uncommenting (remove the starting ';') on the line that reads extension=php_xsl.dll in php.ini on Windows, or apt-get install php5-xsl on most Linux-based systems. For custom builds of PHP, use configure option --with-xsl (requires package libxslt1-dev).

Its necessary install the XLS extension.
My solution by my context.
I'm using one docker container contain ubuntu base and using php-fpm (ie if you simply already use linux ubuntu in the same).
The steps to install this extension in my context were:
First search xsl extension on linux repository
sudo apt-cache search xsl
I ended up finding the php5-xsl, so it was only install
sudo apt-get install php5-xsl
that the installation process the setup configuration is already added, if does not happen, just make yourself
sudo vim /etc/php5/mods-available/xsl.ini
insert this content:extension=xsl.so
(obviously the paths are according to your php configuration settings, but my example is the default configuration)
Restart you php fpm and done (sudo service php5-fpm restart)!
