Question

If I make a variable like this:

val x = <a>H<b>i</b>!</a>

how does Scala represent the text objects? If I were making the system, you’d have some List of elements that looks something like this:

L(0): TextElement = TextElement("h")
L(1): BElement    = BElement(TextElement("i"))
L(2): TextElement = TextElement("!")

But I don’t see anything about text elements in any documentation (or really very much about how this works at all.)

How is it implemented in Scala?

Answer 1

it is xml.Text :

scala> x.child.map(_.getClass).foreach(println)
class scala.xml.Text
class scala.xml.Elem
class scala.xml.Text
