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 nodes? I know how to use { braces } in an XML expression to put a value, but this is a collection of values. Do I need to iterate explicitly or is there something better?
val myXml = <people>{ /* what here?! */ }</people>
The resulting value should be something like:
<people><person><name>joe</name><age>40</age></person>
<person><name>mary</name><age>39</age></person></people>
As it's a functional programming language Array.map is probably what you're looking for:
class Person(name : String, age : Int){
def toXml() = <person><name>{ name }</name><age>{ age }</age></person>
}
object xml {
val people = List(
new Person("Alice", 16),
new Person("Bob", 64)
)
val data = <people>{ people.map(p => p.toXml()) }</people>
def main(args : Array[String]){
println(data)
}
}
Results in:
<people><person><name>Alice</name><age>16</age></person><person><name>Bob</name><age>64</age></person></people>
A formatted result (for a better read):
<people>
<person>
<name>Alice</name>
<age>16</age>
</person>
<person>
<name>Bob</name>
<age>64</age>
</person>
</people>
