Hi Mustafa ,
in PHP multiple (checked with 5.6m and 7.0m , php-fpm )
Compiled libxml version is showing 2.7.6 (if you check phpinfo())
dom
DOM/XML enabled
DOM/XML API Version 20031129
libxml Version 2.7.6
HTML Support enabled
XPath Support enabled
XPointer Support enabled
Schema Support enabled
RelaxNG Support enabled
Is it posible updating this to latest version, or at least to 2.7.8 ?
as it has lost of features that cannot be used on 2.7.6 like
(example
