Missing XML tags for empty IDOC fields

Is there any way to configure or enhance "XML File" IDOC port output logic?

Goal is to generate XML tags for all IDOC fields, even those with empty value. But by default empty fields are skipped in result XML.

Example:

IDOC raw data:

SEGMENT1-MATNR is initial

SEGMENT1-WERKS = "XY01"

XML now:

<segment1 SEGMENT="1">

     <werks>XY01</werks>

</segment1>

XML needed:

<segment1 SEGMENT="1">

     <matnr></matnr>

     <werks>XY01</werks>

</segment1>
