Description

When XMLBuilder is created with both the format and preserveOrder options enabled, the xml string that it produces has values on a separate line and indented. In addition, it adds a newline at the beginning of output.

Code

const XMLdata = `
	<car>
		<color>purple</color>
		<type>minivan</type>
		<registration>2020-02-03</registration>
		<capacity>7</capacity>
	</car>
`;
const parser = new XMLParser({preserveOrder: true});
const builder = new XMLBuilder({preserveOrder: true, format: true});
const output = builder.build(parser.parse(XMLdata));
console.log(output);

Output

<car>
  <color>
    purple
  </color>
  <type>
    minivan
  </type>
  <registration>
    2020-02-03
  </registration>
  <capacity>
    7
  </capacity>
</car>

expected data

<car>
  <color>purple</color>
  <type>minivan</type>
  <registration>2020-02-03</registration>
  <capacity>7</capacity>
</car>

It's difficult to decide when opening and closing tags should be in-lined text data. However, we can provide a configuration for this. But if that is set then even the tags with long text value would be inlined. Which is not expected
