[xsl] generate xpath expression in web links

["David Murphy" <david@xxxxxxxxxxxxxx>]

Hello

Our web app needs to generate the XPath expression that uniquely
identifies a particular node, something like:

<a href="/project[1]/admin[3]/project-manager[5]/full-name[2]">Some
Name</a>

This is what I've come up with so far.

===========================

<a><xsl:call-template name="generatePath"/><xsl:value-of
select="some-link"/></a>

<xsl:template name="generatePath">
	<xsl:attribute name="href">
		<xsl:for-each select="ancestor-or-self::*">
			<xsl:text>/</xsl:text>
			<xsl:value-of select="local-name(.)"/>
			<xsl:text>[</xsl:text>
			<xsl:value-of
select="count(preceding-sibling::*[local-name()=local-name(current())])+
1"/>
			<xsl:text>]</xsl:text>
		</xsl:for-each>
	</xsl:attribute>
</xsl:template>

===========================

It works ok, but I just wanted to check to see if I was missing anything
to make it more efficient. I'm using xslt2.

Thanks, David
