I’m little bit stuck right here, and i require your help =)

So i use the plugin “WP all export” and for one of my client, i have to sort an XML feed base on a template that have to be respected !

So as you know this plugin have an XML editor, but i have some trouble to understand how to do what i want to do with it

My xml feed must look like something like that

<offer>
  <Formation>

    <Action city="Paris"> //Action#1
      <Date Session="01/04/2020">
      </Date>
      <Date Session="20/04/2020">
      </Date>
      <Date Session="12/06/2020">
      </Date>
    </Action>

    <Action city="Madrid"> //Action#2
      <Date Session="01/05/2020">
      </Date>
      <Date Session="04/05/2020">
      </Date>
    </Action>

  </Formation>
</offer>

My wish is to create ( as i show above) multiple “date” by action, and to even multiple “action” but the actual template authorize something like that (without a loop):

<offer>
  <Formation>
    <Action city="Paris">
      <Date Session="01/04/2020">
      </Date>
    </Action
  </Formation>
</offer>

As you can see the second one do not accept a foreach loop to show multiple or multiple inside this action

How can i do this ?

(Apologizes if it’s real bad explains, ask your question i’ll try to answer my best to make a better undestanding of my problem)
