Hi Kurt,
I suggest you first creating a digester rule that helps you handling a
generic ParaItem element:
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));
}
}
then plug the digester rules in the following way:
Digester digester = new Digester();
/* take a look at
http://commons.apache.org/digester/apidocs/org/apache/commons/digester/SimpleRegexMatcher.html
*/
digester.setRules(new RegexRules(new SimpleRegexMatcher()));
digester.addRule("Class/Parameter/Main/*", new ParaItemRule());
digester.addSetNext("Class/Parameter/Main/*", "addMainParaItem");
digester.addRule("Class/Parameter/SubText/*", new ParaItemRule());
digester.addSetNext("Class/Parameter/SubText/*", "addSubParaItem");
THT, let me know! ;)
