The standard scala xml library could make short work of it: The standard Scala XML library

Check out scala String to scala.xml.Elem to convert the string to an scala xml element.
Then you can navigate and parse the xml tree using xpath like sequences in the scala xml library. Something like this:

val xmlNode = scala.xml.XML.loadString(string)
val responseCode = (xmlNode \ "Body" \ "UpdateResponse" \ "responseCode").text
