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

For completeness, you can also use for..yield (or function calls):

import scala.xml

case class Person(val name: String, val age: Int) {
  def toXml(): xml.Elem =
    { name }{ age }
}

def peopleToXml(people: List[Person]): xml.Elem = {
  {
    for {person <- people if person.age > 39}
      yield person.toXml
  }
}

val data = List(Person("joe",40),Person("mary", 35))
println(peopleToXml(data))
