I have Object class like that:

:Class People     
  :Field Public Type ← 'contact'
  :Field Public Company ← ⍬         
  :Field Public Position ← ⍬
  :Field Public Fax ← ⍬
  :Field Public Email ← ⍬
   
  ∇ make args
    :Access Public 
    :Implements Constructor
    Name ← args[1]
    Company ← args[2]
    Position ← args[3]
    ⎕ ← 'New people maked'
  ∇

:EndClass

And I have an array of Objects of People class

  Peoples ← (⎕New People ('Name1' 'Company1' 'Founder')) (⎕New People ('Name2' 'Company2' 'Founder'))
New people maked
New people maked
  Peoples
#.[People]  #.[People]

How do I export Peoples to an xml file? And then import an array from xml?

The task is to save the array and load it from the file when you restart it.
