The original XML files created by your applications might not totally fit the needed specifications for the Automotive package. Issues can be missing information in the XML, or perhaps the layout is wrong, so that you need to rearrange the file before processing.
In such situations you should consider to run the input XML file through a transform definition in InterFormNG, to change the contents of the input XML file.
The implementation of this depends on, if the input XML file should be validated or not.
If the transformed (changed) input XML file does not need to be validated, then you can simply add the XSLT needed on the specific action in the InterFormNG workflow to transform the input XML file to the correct format. If validation is enabled, the original (unchanged) file will be attempted to be validated, but validation will take place only in certain conditions.
If you want to validate the transformed file, then you need to change the workflow, so that the original XML file triggers a rule, that transforms the contents (but without any action specified). The transformed XML file should be triggered by another rule, that executes an action an cause the validation.
You need to enable processing transformed XML files.
