Fuse Mediation Router has a built-in API that enables you to perform simple transformations on
incoming and outgoing messages. For example, the route shown in
Example 7.1 appends the text, World!, to the end of
the incoming message body.
Example 7.1. Simple transformation of messages
<from uri="SourceURL" /> <setBody> <language language="constant">World!</language> </setBody> <to uri="TargetURL" />
Where the setBody pattern replaces the content of the
incoming message's body based on an expression.
Fuse Mediation Router provides the patterns listed in Table 7.1 for doing simple, expression based, transformations.
