Removing nodes from XML
You can use RuleTransformer from scala.xml.transform.
Suppose you have action attribute with "remove" value
val removeIt = new RewriteRule { override def transform(n: Node): NodeSeq = n match { case e: Elem if (e \ "@action").text == "remove" => NodeSeq.Empty case n => n } }new RuleTransformer(removeIt).transform(yourXML)
