I'm new to XML/XSL and would appreciate any assistance. I would like to traverse the <event> tag and retrieve all the info as a single text record. But I'm having trouble with extracting the remaining <participants> and <entity> info (see expected output). So far, only managed to display partial info. Below are the given xsl & xml files.
Thanks in advance.

EXPECTED OUTPUT
================
1 , PHYSICS , Monday , 8:00 , 10:00 , 1A , Bush , Lab
2 , MATHS , Tuesday , 16:00 , 18:00 , 1A , Clinton , TutRm 1-2
1 , PHYSICS , Wednesday , 10:00 , 12:00 , 1A , Bush , Lab
3 , POLITICS , Thursday , 13:00 , 16:00 , 1A , Bush + Clinton , TutRm 1-1
