Can I edit xml using scala?

Question

Given that i have a Node

var xml = XML.loadFile("some/file/here")

what can i do should i want to change the value of some element to a new value

That is,

...
<anElement>5</anElement>
...

to

...
<anElement>blooblahblahyah</anElement>
...

Apologies if this is a pretty silly question, i'm incredibly new to Scala and haven't found any definitive answer on xml editing.

The Node is immutable and this makes editing it a bit tedious.
There are examples in the Scala XML book.

val foo = <foo><bar>1</bar><bar>2</bar></foo>
foo.copy (child = foo.child.map {case bar: scala.xml.Elem =>
  bar.copy (child = scala.xml.Text ((bar.text.toInt + 1).toString))})

res0: scala.xml.Elem = <foo><bar>2</bar><bar>3</bar></foo>

Also take a look at xml.transform: scala-lang.org/api/current/… ; couple of examples: daily-scala.blogspot.ru/2009/12/xml-transformation-1.html
