break;
case XMLStreamConstants.END_ELEMENT:

+ event.asEndElement().getName() +"\n");
spacer.delete( (spacer.length() - 2), spacer.length() );
break;
case XMLStreamConstants.ATTRIBUTE:
break;
default :
break;
}
}

Das funktioniert soweit , nun möchte ich allerdings das die geparste Datei wieder zurück nach
XML konvertiert wird wie kann man das machen ??
Danke für die Hilfe
