You mean:

        digester.addObjectCreate("article", Article.class);
        digester.addSetProperties("article", "id", "id");=20

Yup. I've tried that. The actual value of the id field in the XML
"_1234" is ignored and "0" is set on the Article id field instead. I
assume that this is because of the underscore in the id field.

Have you tried an ObjectCreate followed by a SetProperties?
