Exclude Fields from the Output
This DataWeave example excludes specific XML elements from the output. You might perform a task like this to remove sensitive data. Before you begin, note that 2.x versions of DataWeave are used by Mule 4 apps. For DataWeave in Mule 3 apps, refer to DataWeave version 1.2 examples. For other DataWeave versions, you can use the version selector in the DataWeave table of contents.
The example uses these functions:
-
-
to remove specifickey:value
pairs (here, thessn
andpassword
XML elements). -
mapObject
to go through the XML elements.
