Recursive call for try in scala

I am trying to extract currency from YQL in scala. getXML mentioned below takes the rest URL and returns the xml node. In my main code i would like to call getXML again in case failure happens after a sleep of 10000 milli seconds.

Kindly advise how can be achieved as when i am trying to make a getXML inside the failure code is not compiling.

def getXML(url: String): Try[scala.xml.Node] =  
 {

 Try(XML.loadString(Source.fromURL(new URL(url)).mkString))

 }


val nodes = getXML(ccyurl) match {
  case Success(node) => node
  case Failure(f) => {
      Thread.sleep(10000)
      /****/
}
