XMLDBCollectionGenerator
public class XMLDBCollectionGenerator extends ServiceableGenerator implements CacheableProcessingComponent,Configurable,Initializable(Code)
This class implements generation of a XML:DB collection contents as a directory listing.
 <driver>
 (a valid DB:XML compliant driver)
 </driver>
 <base>
 xmldb:yourdriver://host/an/optional/path/to/be/prepended
 </base>
 
NOTE: the driver can be any DB:XML compliant driver (although this component has been tested only with dbXML, and the trailing slash in the base tag is important!
