Transform XML to JSON

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 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.

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.
