You might select the nearest preceding sibling like this,

        <xsl:for-each select="/root/orange/preceding-sibling::*">
            <xsl:if test="position() = last()">
                <xsl:value-of select="name(.)"/>
                 ...
            </xsl:if>
        </xsl:for-each>


Hope this is what you want.

Lisa

Lisa,

Thank you very much.  If you don't mind, I've run into another issue
today with referencing the preceding element.  Here is an example:

<root>
   <apple/>
   <pear/>
   <orange/>
</root>

Given an xpath to orange (/root/orange) I want to reference the
previous element which is a peer.  I tried the following with no
success:

   /root/preceding::orange

I'm sure this is dreadfully simple, but I'm drawing a blank and I'm
not seeing the answer in the tutorials I'm reading.
