This extension requires the libxml PHP extension. This means passing the --with-libxml, or prior to PHP 7.4 the --enable-libxml, configuration flag, although this is implicitly accomplished because libxml is enabled by default.
This extension uses libxslt which can be found at » https://gitlab.gnome.org/GNOME/libxslt/-/wikis/home. libxslt version 1.1.0 or greater is required.
