Java, Digester: order of processing the XML nested branches

I want to process an XML file where the entries are nested.

    Digester d = new Digester();
    d.setValidating(false);
    d.push(new Object() {
        public void addMessage(final String id, final String text) {
            System.out.writeln ("Message");
        }

        public void addObject(final String className, final String index) {
            System.out.writeln ("Object");
        }
    });

the XML:

    <message id="id">
        <object className="sdsdf" index="2234"></object>
    </message>

    <message id="id2" text="sdfsdfsdfsdf">
        <object className="1" index="1"></object>
        <object className="2" index="12"></object>
        <object className="3" index="13"></object>
    </message>

this will process it with the following order:

object
message
object
object
object
message

but I want it in linear

message
object
message
object
object
object

because I want to build a real tree, so first message must come, then its objects
