Whitespace removal from XML

[harryh]

Not scrictly a Lift question, but does anyone have a library they like
(or is there something in scalalib I'm not aware of) that will remove
whitespace from XML?

<foo>
  <bar>hello world</bar>
</foo>

to:

<foo><bar>hello world</bar></foo>

Answering my own question, I wrote this.  I think it should do what I
want:

def compactXml(node: Node): Node = node match {
  case Elem(p, l, a, s, children @ _*) => Elem(p, l, a, s, children.map
(compactXml(_)) :_*)
  case Text(data) => Text(data.trim)
  case x => x
}
