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...
