Read a {@link InputStream} into an {@link OpenImmoTransferDocument} or
{@link OpenImmoFeedbackDocument} and print some of their content to
console.

@param xmlInputStream the input stream to read
@throws SAXException                 if the file is not readable by the XML parser
@throws IOException                  if the file is not readable
@throws ParserConfigurationException if the XML parser is improperly configured
@throws JAXBException                if XML conversion into Java objects failed
