  Called when the end of an element is reached.

  Specified by:
    `endElement` in interface `ContentHandler`
  Overrides:
    `endElement` in class `DefaultHandler`
  Parameters:
    `poNameSpace` - a `String` - the name space.
    `poElementName` - a `String` - the local element name.

### characters

    public void characters(char[] charBuffer,
                           int start,
