Kevin SawyerSubject: Mapping XSD

If I choose to map from an XSD instead of an XML file, I have no data to preview. How do I assoicate sample XML?
Thanks,
Kevin

Hi Kevin,
you can associate the data to preview by entering the file name in the scenario dialog. If you don't have a sample file you can use the document wizard "XML Schema to XML" as a starting point.

Hope this helps,
Alberto

Thanks again Alberto.

The implication is that we always start from XML even though it may be fully generated from the underlying XSD. Is that correct?

If so, what happens when the schema changes? Do we regen using the same XML file name?

Hi Kevin,
an XSLT stylesheet must be applied to an XML file, even if you created it by reading an XSD. If you are designing a mapping you can work on data generated by a generator, but in the end you will have to run the conversion on real data.
What happens if the schema changes? Well, if the changes are limited to the location of nodes, or to their cardinality, it could be that the XSLT still works; if the changes are more structural (nodes added/removed/renamed) you will have to change your stylesheet accordingly.

Alberto
