How to get elements in a row?

Hi, 

How I can get elements in a comma separated row without last comma and
header line?
Each item should have its features (one, two, three, four) but also its
parent (sample1).
I am using xalan java processor 2.2.d13.

Wanted Output
******************************************************
sample1,item1,one,two
sample1,item2,three,four
******************************************************

Current Output
******************************************************
<?xml version="1.0" encoding="UTF-8"?>
sample1,
item1,
one,
two,
item2,
three,
four,
