The XML output generates a xml representation of the generated output. This example
is a small educational outputtarget, to show the global concepts of the OutputProcess.
It is kept small and simple.
The target consists of 2 parts. The XMLProcessor is used to prepare the report and
to initialize the XMLWriter.
The XMLProcessor
The XMLProcessor instantiates the XMLWriter. The Processor is also used to repaginate
the report; this is the report preparation process which calculates function values and
resolves function dependencies. Finally, the last report processing run activates the
XMLWriter, which writes the generated output to a java.io.Writer.
The XMLWriter
The XMLWriter is a report function. For every received event, the to be printed band is
simply written as XML-Stream.
