[xsl] position

Hello,

     I am trying to find number of tags in my xml using XSLT. The XSLT is

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:output method="text"/>
	<xsl:template match="/">
			<xsl:apply-templates select="dataroot/ReferenceTaskDb[last()]"/>
	</xsl:template>
	<xsl:template match="ReferenceTaskDb">
		<result> <xsl:value-of select="position()"/></result>
	</xsl:template>
</xsl:stylesheet>

   It is returning 1. What is the wrong here ?

Thanks and Regards,
Chandu
