Scala: Select following sibling in xml

Is there any way to select following sibling element in xml using Scala?

So if I have xml like this:

<root> <childA>A</childA> <randomElementName>B</randomElementName> </root>

I would like to do selection like this:

(root \ "childA") followingSibling text

that will give me "B"

I guess it's not as elegant as you expected, but it works:

root.
  child.
  dropWhile{ _.label != "childA" }.
  collect{ case e: xml.Elem => e }.
  drop(1).
  headOption.
  map{ _.text }
// Option[String] = Some(B)

There is no XPath in scala.xml, so you should work with it as with collection.
