Description

It is often required to copy/replace message content from/with a specified source such as a inline xml, localentry or a property. Also we need to store a given message to a property or create a custom message from a given source.
Enrich Mediator can process a message based on a given source configuration and then perform the specified action on the message by using the target configuration. It basically gets an OMElement using the configuration specified in the source and then modify the message by putting it on the current message using the configuration in the target.

Syntax:
<enrich>
<source [clone=true|false] [type=custom|envelope|body|property|inline] xpath="" property="" />
<target [action=replace|child|sibiling] [type=custom|envelope|body|property|inline] xpath="" property="" />
</enrich>

Enrich Mediator that is included in this patch facilitates these requirements.
