Output Self-closing XML Tags

For XML, DataWeave by default outputs every value within an opening and closing tag, even if the tag contains no value (for example, <element2></element2>). Before you begin, note that DataWeave 2.0 (%dw 2.0) is for Mule 4 apps. For a Mule 3 app, refer to DataWeave 1.0 (%dw 1.0) examples, within the Mule 3.9 documentation set. For other Mule versions, you can use the Mule Runtime version selector in the table of contents.

To output empty tags as a self-closing XML element (for example, <element2/>), you can set the inlineCloseOn="empty" output directive in the DataWeave header.

DataWeave Script:
%dw 2.0
output application/xml inlineCloseOn="empty"
Input JSON Payload:
    "userName": "John Doe",
Output XML:
<?xml version='1.0' encoding='UTF-8'?>
  <userName>John Doe</userName>
