[xsl] Counting the number of elements in a variable before looping

[sudheshna iyer <sudheshnaiyer@xxxxxxxxx>]

I need to find out how many elements are present in
the variable "computers" in the below for-each.

<xsl:for-each select="$computers">

I need to display a message to the user based on the
number of elements that are present.

Is there any variable called count for doing the above?
