Digester: Extracting node name

Question

Is it possible to extract the node name using apache digester?

So, if the xml looks like

   
     
       .....
              


        

Answer 1

This is the kind of matching that ExtendedBaseRules afford.

Let's say this is the content of furniture.xml:

Let's say you want to get the element names of the direct children of furniture element. This is what furniture/? matches in the ExtendedBaseRules.

import java.io.*;
import java.util.*;
import org.apache.commons.digester.*;

public class FurnitureDigest {
    public static void main(String[] args) throws Exception {
        File file = new File("furniture.xml");
        Digester digester = new Digester();
        digester.setRules(new ExtendedBaseRules());
        final List furnitures = new ArrayList();
        digester.addRule("furniture/?", new Rule() {
            @Override public void end(String nspace, String name) {
                furnitures.add(name);
            }
        });
        digester.parse(file);
        System.out.println(furnitures); // prints "[sofa, coffeeTable]"
    }
}
