Ni hao again Kurt,
just realized that the ParaItemRule implementation is incomplete, use
the one below.
Simo
public final class ParaItemRule extends org.apache.commons.digester.Rule {
@Override
public void body(String namespace, String name, String text)
throws Exception {
digester.push(new ParaItem(name, text));
}
@Override
public void end() throws Exception {
digester.pop();
}
