Descomenta la linea de tu php.ini, pero no quites el DLL, es un bug al parecer, lee esto:
Cita: If you use PHP 5 in windows, you don't need to declare
php_domxml.dll in your php.ini file.
so u can give comment in the line php_domxml.dll in your
php.ini file.
you only need to comment it out, but do not delete the
php_domxml.dll file in the ext directory.
Saludos
