Very handy!

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

StreamingTransform myTransform = new StreamingTransform() {
     public Nodes transform(Element subtree) {
         System.out.println(XQueryUtil.xquery(subtree, 
"name").get(0).getValue());
         System.out.println("of");
         System.out.println(XQueryUtil.xquery(subtree, 
"address/city").get(0).getValue());
         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...
