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 DataWeave example changes the values of some XML elements. Here, it changes the values of keys containing sensitive data to a set of asterisks (****
).
It uses these functions:
-
mapObject
to go through the users in the input. When on each user, it uses two othermapObject
functions to go through the fields in both personal information and the login information. -
if
andelse
to mask the values of thessn
andpassword
keys.
