I saw that in the list archives it was not supported but
1) is it planned to be able to support something like
digester.addCallMethod("[EMAIL PROTECTED]"blah"\]", "foo"); ?
(simon's covered this pretty well. a long time ago scott knew most about this so if he's still around, now would be a good time for him to jump in ;)
2) is there a way around it currently?
I see that all the rules have a way to see the attributes before processing
but I don't know how to stop that rule from processing.
if stopping a rule firing on the basic of attributes, that can be done by a wrapper Rule implementation. this should test the attributes and only execute the rule if they match your expectations. the only wrinkle is that you'll probably need to push the implementation onto the stack. here's the type of thing i mean (not tested and with badly named methods):
public interface AttributesApprover {
public boolean approved(Attributes attributes);
}public class doNothingRule extends Rule {}
public class AttributesFilter extends Rule {
private ArrayStack ruleStack = new ArrayStack();
private AttributesApprover approver;
private Rule rule;
public void begin(String namespace, String name, Attributes attributes) {
if (approver.approve(attributes)) {
ruleStack.push(rule);
} else {
ruleStack.push(new DoNothingRule());
}
((Rule)ruleStack.peek()).begin(namespace, name, attributes);
}
public void body(String namespace, String name, String text) { ((Rule)ruleStack.peek()).body(namespace, name, text);
}
public void end(String namespace, String name,) { ((Rule)ruleStack.pop()).end(namespace, name,);
}
}
