I received a question in the form of a comment on using XML files here. Fittingly, we were discussing this exact topic yesterday and I decided I would try it out.

So here goes.

You'll need 2 files: a XML file and a XSL stylesheet (which defines the XML file). I found said files here. I'll also provide them here (cdcatalog.xml) and here (cdcatalog.xls).

In the Administration tool, go to File --> Import --> from Database

When you prompted to select a datasource, select XML and the window should look like this

For URL, browse to the location you saved cdcatalog.xml, do the same for XSLT

Hit OK and you'll be prompted with the Import dialog

Import the "table" and you're done.
