Answer 1

What PHP version are you using? You need to ensure that make sure you have the domxml library/extension.

Answer 2

you can see the requirements here. Quote:

This extension makes use of the » GNOME XML library. Download and install this library. You will need at least libxml-2.4.14. To use DOM XSLT features you can use the » libxslt library and EXSLT enhancements from » http://www.exslt.org/. Download and install these libraries if you plan to use (enhanced) XSLT features. You will need at least libxslt-1.0.18.
