XML Parser
Description
This unit is a Processor unit type.
The XML Parser unit parses events containing a properly formatted XML, using the Jackson parser.
An event comes in through the in port. The data field content is parsed using Jackson.
Successfully parsed input events are enriched with a new field containing the parse result and are output through the out port.
If an error occurs, the input event is enriched with new fields describing the problem, and the event is sent through the error port.
