Output Self-closing XML Tags

DataWeave 2.1 is compatible with Mule 4.1. Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule will reach its End of Life on November 2, 2022, when Extended Support ends.

Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.

MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.

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>).

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.

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