Prakash,

The above stylesheet works fine as long as there are more than 1 nodes.

If there is only one than below statement

> <xsl:when test="position() = last()">

Never gets evaluated. I am attempting to repair this now... any ideas ?

What I was thinking was something along the lines of the following
pseudo code, although I do not know how to implement it in xsl. I hope
the following makes some sense !

lastParameterWritten=false
Choose
When test="position()=1"
	Write first parameter
End when
When test="position()=last()"
	Write last parameter
	Set lastParameterWritten = true
End when
End Choose

If test="lastParameterWritten=false"
	Write currentParameter as last
End if


Thanks
Joe
