Re: accessing last element of node set passed as param

I'm trying to figure out how to access the last element

For example, with:

    <xsl:template match="FOO">
        <xsl:param  name="result"  select="/.." />
        <xsl:variable  name="prior"  select="$result/BAR[last()]" />
        <!-- Something done it is -->
    </xsl:template>

if "FOO" is matched, and the parameter, "result", is assigned the node set

<BAR i=1/><BAR i=2/><BAR i=3/>

what expression would I need to access the last "BAR" element

You are trying to select the last of BAR *children* of anything
in the passed node set. Try select="$result[last()]", though I'm
not sure it'll work either.
