Release : 15.7.1
Component : CA PPM APPLICATION
Tibco (Jaspersoft) do not have the XML Export as a standard functionality. They have a default JR XML Exporter class as below which you have also found:http://jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/export/JRXmlExporter.htmlbut this will output to a proprietary XML structure format which may not be the structure you want.Hence you have to write your own custom XML exporter to produce your own XML output.
There is a section on XML Exporter in the JasperReports Library Ultimate Guide (page 258) that you can refer to. This document can be downloaded from the community docs section here:https://community.jaspersoft.com/documentation/jasperreports-library-ultimate-guide
