Hi,
I have an xml document that contains a list of events and uses ID and IDREF to normalize people or persons. So one person could be involved in two different events and they are referenced through IDREF.
have the xml document and xsd shown below.
I would like to use xsl to denormalize this and display the list or collection of events with the person's data (basically name) brought into the event. If one person is involved in multiple events then their data would displayed multiple times.
How could I do this with xsl?
Thanks!!
