I can not resist to present a much shorter solution using XMLBeam that works with any number of "detail-x" subelements.

public class Tetst {

@XBDocURL("resource://test.xml")
public interface Projection {
    @XBRead("name()")
    String getName();

    @XBRead("./detail")
    List getDetailStrings();

    @XBRead("/Details/*")
    List getDetails();
}

@Test
public void xml2Hashmap() throws IOException {
    HashMap> hashmap = new HashMap>();
    for (Projection p : new XBProjector().io().fromURLAnnotation(Projection.class).getDetails()) {
        System.out.println(p.getName() + ": " + p.getDetailStrings());
        hashmap.put(p.getName(), p.getDetailStrings());
    }
}
}

This prints out

detail-a: [ attribute 1 of detail a ,  attribute 2 of detail a ,  attribute 3 of detail a ]
detail-b: [ attribute 1 of detail b ,  attribute 2 of detail b ]

for your example test.xml and fills a Hashmap.
