I want to know , can we load xsd file instead of xml file in bi publisher to generate report.
not instead of
it's may be additionally
xsd is not data. it's description http://en.wikipedia.org/wiki/XML_Schema
when you create data template you add "Data Template" file (it's how you get data for report. it's sql statement) and you can add "XML Schema" file
for preview you add "Preview Data" file with sample data
But my question is , can we load .XSD data file instead of .XML data to generate report.?
instead of - no
additionally - yes
you can add only xsd file to definition of data template if data com from fnd_file.put_line(fnd_file.output, '.....') but it's also equal xml+xsd not only xsd
