Transform XML to JSON

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.

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.

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.
