Subject: Recursive XSL From: Hakan Bilgin Date: February 2, 2005

Below is my first recursive XSL. Feel free to use it (dont forget to give me credits...tihi). Also if you improve I would be very happy if you shared your modification to "moi"...

your pal,
Hakan

PS: When testing this code you will be promted because xml-island points to http://www.challenger.se/test.xml. If you want you can test it with your own xml-files.Just change the source attribute...DS
