 Title   : characters
 Usage   : $eventgenerator->characters($str)
 Function: Send a character events
 Returns : none
 Args    : string

 Title   : end_document
 Usage   : $eventgenerator->end_document();
 Function: Handle an end document event
 Returns : none
 Args    : none
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'
in_elementcodeprevnextTop
 Title   : in_element
 Usage   : if( $eventgenerator->in_element($element) ) {}
 Function: Test if we are in a particular element
           This is different than 'within' because 'in' tests only
           if one has reached a specific element.
 Returns : boolean
 Args    : string element name
start_documentcodeprevnextTop
 Title   : start_document
 Usage   : $eventgenerator->start_document();
 Function: Handle a start document event
 Returns : none
 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'
will_handlecodeprevnextTop
 Title   : will_handle
 Usage   : if( $handler->will_handle($event_type) ) { ... }
 Function: Tests if this event builder knows how to process a specific event
 Returns : boolean
 Args    : event type name
within_elementcodeprevnextTop
 Title   : within_element
 Usage   : if( $eventgenerator->within_element($element) ) {}
 Function: Test if we are within a particular element
