How to make XStream skip unmapped tags when parsing XML?

Question

I have a large XML document that I want to convert to a Java bean. It has a lot of tags and attributes, but I'm interested only in a handful of those. Unfurtounately, it seems that XStream forces you to declare a property in that bean for each and every tag that may ever be in that XML. Is there a way around this?

Initialize XStream as shown below to ignore fields that are not defined in your bean.

XStream xstream = new XStream() {     @Override     protected MapperWrapper wrapMapper(MapperWrapper next) {         return new MapperWrapper(next) {             @Override             public boolean shouldSerializeMember(Class definedIn, String fieldName) {                 if (definedIn == Object.class) {                     return false;                 }                 return super.shouldSerializeMember(definedIn, fieldName);             }         };     } };
