(Contractors have an easy life (no flames pls)...)

I thought I would provide a 2.0 solution

In 2.0 you can save your fingers as its much shorter:

<xsl:stylesheet version="2.0"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
	<nos>
		<xsl:for-each select="for $i in //data return tokenize($i, ',')">
			<no><xsl:value-of select="."/></no>
		</xsl:for-each>
	</nos>
</xsl:template>

</xsl:stylesheet>
