Re: [xsl] Path according to a child node attribute

Hi all,

I have posted a similar question two days ago see
http://www.biglist.com/lists/lists.mulberrytech.com/xsl-list/archives/201112
/msg00325.html in order to create a Path according to a child node attribute
Only, there is a slightly change which adds other Rubric elements with more
kind attributes and inside them, two Label elements for the language chosen:

<?xml version="1.0" encoding="UTF-8"?>

        <Class code="B">

                </Rubric>
        </Class>
</root>

The output should be similar like this:

                        <Label xml:lang="en">BODY FUNCTIONS</Label>
                </Rubric>

                </Rubric>
                <Path>B FUNZIONI CORPOREE/b1 FUNZIONI MENTALI</Path>

                </Rubric>
                <Path>B FUNZIONI CORPOREE/b1 FUNZIONI MENTALI/b110-b139
FUNZIONI MENTALI GLOBALI</Path>
        </Class>
        ...


The aim is the same, now it must be chosen the text inside the <Label
xml:lang="it"> inside <Rubric kind="preferred"> since there are more kind
attributes for <Rubric> element.

Here's the code provided by Martin Hennen which works great if there is only
one <Rubric> element without attribute and inside some text:

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

  <xsl:key name="k1" match="Class" use="@code"/>

   <xsl:template match="@* | node()">
     <xsl:copy>
       <xsl:apply-templates select="@* | node()"/>
     </xsl:copy>
   </xsl:template>

   <xsl:template match="Class">
     <xsl:copy>
       <xsl:apply-templates select="@* | node()"/>
       <Path>
         <xsl:apply-templates select="key('k1', SuperClass/@code)"
mode="path"/>
       </Path>
     </xsl:copy>
   </xsl:template>

   <xsl:template match="Class" mode="path">
     <xsl:variable name="next" select="key('k1', SuperClass/@code)"/>
     <xsl:if test="$next">
       <xsl:apply-templates select="$next" mode="path"/>
       <xsl:text>/</xsl:text>
     </xsl:if>
     <xsl:value-of select="concat(@code,' ', Rubric)"/>
   </xsl:template>

</xsl:stylesheet>

Many thanks if someone can suggest
