  4. Perform a Basic Transformation

Transform XML to JSON

DataWeave 2.2 is compatible and bundled with Mule 4.2. This version of Mule reached its End of Life on May 2, 2023, when Extended Support ended.

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.

This simple DataWeave example changes the XML input to JSON output by using selector expressions without any functions. It also changes the order and names of some of the fields. Note that more complex transformations usually require the use of the map or mapObject function. Before you begin, note that DataWeave version 2 (%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.

The DataWeave script maps the names (or keys) for the output fields to values of the input fields. The input fields are specified with selector expressions.
