No, handling comments is not possible in Digester as far as I know (AFAIK). In order to be informed of comments by the sax parser, Digester would need to implement the org.xml.sax.ext.LexicalHandler interface, and it does not. The "normal" org.xml.sax.ContentHandler interface which Digester uses doesn't get notified of comments. You might be able to do something like create your own XMLParser instance and point it at your own filter class which implements ContentHandler and LexicalHandler. Your filter could then delegate ContentHandler methods through to a Digester instance. When the filter is notified of a comment it could access the digester stack to do stuff. However it doesn't sound terribly easy to me...
