This isn't quite what you want, but it may help...
Define this template first:
<xsl:template match="*" mode="whereAmI">
<xsl:param name="location"/>
<xsl:choose>
<xsl:when test="name(.) = 'root'">Location = <xsl:value-of
select="name(.)"/> / <xsl:value-of select="$location"/> </xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="parent::*" mode="whereAmI">
<xsl:with-param name="location"><xsl:value-of
select="name(.)"/><xsl:if test="string($location) != ''"> /
<xsl:value-of select="$location"/></xsl:if></xsl:with-param>
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Then, when you need to know "where you are", call this one.
<xsl:apply-templates select="." mode="whereAmI"/>
It should return *if* 'inside' <c/> (with your data)...
"Location = root / a / b / c"
Cheers,

hello, having some trouble making this work: within my stylesheet,
i have selected a node somewhere in the midst of the document tree,
several nested elements deep. what i would like to do is, given
this node N (at arbitrary depth), walk *back* up the document tree
hierarchy, element by element, printing the successive parent elements
(technically, printing each element's "name" @ribute).
so with node N being <c> and the following document:
<root>
<a>
<b>
<c/>
</b>
<d/>
<e/>
</a>
</root>
i want to print: b, a, root.
my pseudocode was along the lines of:
current = node
while current != root
current = ../
print current/@name
seems simple.
recursive templates seemed like the way to do this in xsl, but i
can't get this to do anything, apparently because the processor i'm
using (sablotron 0.90) won't let me use XPath on the node set i am
passing with call-template (as a param) because it's "not a node-set".
so i guess i have two questions:
1. what is the best algorithm/approach to walk back up the parent:: tree,
printing each element?
2. does sabcmd not have a node-set() function? is this what's stopping me?
(if it helps, the stylesheet will know what depth level the current
node is at, and the unique @name attribute of each parent element.)
