  1. You can use xml2 utility (https://manpages.debian.org/jessie/xml2/2xml.1) and starting in example from

  2. I assume you'd like to convert spreadsheet(-like) xml files. Then it looks like the Gnumeric package can do what you need.
    To install it:

    sudo apt install gnumeric

    It provides the CLI utility ssconvert which is, as the manpage says,

    a command line spreadsheet format converter

    To use it:

    ssconvert SOURCE_FILE DEST_FILE

    If instead you want a more "generic XML to CSV converter", I cannot think of a pre-packaged tool installable in Ubuntu.
    A quick googling suggest this GitHub repository. It's java based, but it should work ok in Ubuntu.
