I want to composer update but, it gives me error like this.
Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for phpoffice/phpexcel 1.8.0 -> satisfiable by phpoffice/phpexcel[1.8.0].
- phpoffice/phpexcel 1.8.0 requires ext-xml * -> the requested PHP extension xml is missing from your system.
To enable extensions, verify that they are enabled in those .ini files:
- /etc/php/7.0/cli/php.ini
- /etc/php/7.0/cli/conf.d/10-opcache.ini
- /etc/php/7.0/cli/conf.d/10-pdo.ini

You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
