[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Counting Nodes Based on Conditional Statements
 Anyway, I have a stylesheet that displays book titles depending on some parameters passed to it. As a result, a dynamic number of books are shown. I need to count the number of the book titles that are shown, and display the result accordingly. If no book titles are shown at all, I need to be able to display message in their absence. Only containing a cursory knowledge of variables in XSLT, i'm not yet skilled enough to handle this problem on my own. Some help would be great. An example of the xml document follows: <category name="Health & Fitness">
