Howdy, Try this at the Scala REPL (the Scala command line): scala> if (true) <d/>
scala> The type of a if expression (without and else) is always Unit. Unit is always blank in XML, and thus you never get anything. Please change to if (true) <d/> else NodeSeq.Empty scala> import scala.xml._ import scala.xml._ scala> if (true) <d/> else NodeSeq.Empty res1: scala.xml.NodeSeq = <d></d> And it works.
