Hi.
>what book would you suggest for the basics?
Hard to say. Most XML books seem to have at least one chapter on XSL. The only pure XSLT books I have are the Wrox "XSLT Programmer's Reference" (which isn't ideal as a tutorial text) and O'Reilly's "XSLT" (which is OK).
If you'll be using MSXML you could try this site first :
