simple cases you can get by as above, but usually you have to use a
node-set extension function for this sort of thing (until xslt 1.1)
for instance if you wanted to apply normalize-space to each of your
nodes in the node set before computing your average, you'd do something
like
<xsl:variable name="x">
<xsl:for-each select="[nodeset]" >
<x><xsl:value-of select="string-length(normalize-space(.))"/>
</xsl:for-each>
</xsl:variable>
<xsl:value-of select="sum(xt:node-set($x)/x)"/>
