Scala: how to create XML nodes from some collection

Question

If you have something like:

val myStuff = Array(Person(\"joe\",40), Person(\"mary\", 35))

How do you create an XML value with that data as

Answer 1

As it's a functional programming language Array.map is probably what you're looking for:

class Person(name : String, age : Int){
    def toXml() = { name }{ age }
}

object xml {
    val people = List(
        new Person("Alice", 16),
        new Person("Bob", 64)
    )

    val data = { people.map(p => p.toXml()) }

    def main(args : Array[String]){
        println(data)
    }
}

Results in:

Alice16Bob64

A formatted result (for a better read):

   
      Alice
      16
   
   
      Bob
      64
