next_resultcode    nextTop
 Title   : next_result
 Usage   : my $hit = $searchio->next_result;
 Function: Returns the next Result from a search
 Returns : Bio::Search::Result::ResultI object
 Args    : none
start_elementcodeprevnextTop
 Title   : start_element
 Usage   : $eventgenerator->start_element
 Function: Handles a start element event
 Returns : none
 Args    : hashref with at least 2 keys 'Data' and 'Name'
end_elementcodeprevnextTop
 Title   : start_element
 Usage   : $eventgenerator->end_element
 Function: Handles an end element event
 Returns : none
 Args    : hashref with at least 2 keys 'Data' and 'Name'
elementcodeprevnextTop
 Title   : element
 Usage   : $eventhandler->element({'Name' => $name, 'Data' => $str});
 Function: Convience method that calls start_element, characters, end_element
 Returns : none
 Args    : Hash ref with the keys 'Name' and 'Data'
characterscodeprevnextTop
 Title   : characters
 Usage   : $eventgenerator->characters($str)
 Function: Send a character events
 Returns : none
 Args    : string
within_elementcodeprevnextTop
 Title   : within_element
 Usage   : if( $eventgenerator->within_element($element) ) {}
 Function: Test if we are within a particular element
           This is different than 'in' because within can be tested
           for a whole block.
 Returns : boolean

 Title   : in_element
 Usage   : if( $eventgenerator->in_element($element) ) {}

 Title   : wise
 Usage   : $obj->wise($newval)
 Function: Get/Set the Wise object parser
 Returns : value of wise (a scalar)

address it. Please include a thorough description of the problem
with code and data examples if at all possible.
