How do I add an XML attribute, or not, depending on an Option?

Question

I have written a makeMsg function but I don\'t like it - it just seems really un-Scala-ish to discriminate based on Option.isDefined. Can you make it better?

Answer 1

Canonical Scala that does not require the text field to know to cleverly disappear when it's empty:

t.map(s => ).getOrElse()

You should think about using this pattern whenever you have an option but need to use something that doesn't know about options. (In this case, Easy Angel has found a more compact solution where it does know about options or something like them.)
