Re: [xslt] How can I tell the type of output I receive?

[Dave Hyatt <hyatt apple com>]

Worked like a charm.  I now have simple XSL transformations working!  
(Cheer.)  Thanks for the help.

Anyone have any good pointers to XSL examples that use 
<?xml-stylesheet...> to load the XSL files?  I tested with the ones on 
devedge.netscape.com, but any other examples would be much appreciated, 
especially ones that output HTML that wants to load subresources (like 
images, scripts, or CSS files).
