Thanks and I have tried with attached example xml with XSD file but CSV formatter failed with data need to flatten output of json parser. but CSV requirement is same.
XML file reading from Folder and XML file some elements May or may not come but If elements come then CSV file should have elements header and value else CSV file should have element header with blank value
