Very handy!

FYI, analog example Java code for the current Nux version reads as 

StreamingTransform myTransform = new StreamingTransform() {
     public Nodes transform(Element subtree) {
         return new Nodes(); // mark current element as subject to 
garbage collection
Builder builder = new Builder(new StreamingPathFilter("/labels/label", 
null).createNodeFactory(null, myTransform));
builder.build(new File("labels.xml"));

It's not as compact as with Amara, but still quite handy...
