New Data Connection with incoming XSLT. Should DataView show the structure?

[Former Community Member]

When I Create New Data Connection with an XML file and an incoming XSLT transformation, the Data View doesn't show the resulting structure..just the original XML file structure. This makes it hard to bind xml elements in the transformation to a PDF form. It the XSLT only applied at "runtime"? If so, how to map elements? Thanks.
