I need to concatenate the "name" attributes of all of the parents for
each element. All I could figure out was to use a recursive template.
Is there a more straightforward way to accomplish this?



XML:

<Dataset name="root">
     <A name="a1">
         <A name="a2">
             <A name="a3" />
         </A>
     </A>
     <B name="b1">
         <B name="b2"/>
     </B>
</Dataset>

Desired output:

<fullName>a1</fullName>
<fullName>a1.a2</fullName>
<fullName>a1.a2.a3</fullName>

<fullName>b1</fullName>
<fullName>b1.b2</fullName>


XSL:

     <xsl:template name="fullName">
         <fullName>
             <xsl:call-template name="fullNameWorker" />
         </fullName >
     </xsl:template>

     <xsl:template match="*" name="fullNameWorker" mode="fullName">
         <xsl:if test=".!=/">
             <xsl:apply-templates select=".." mode="fullName"/>
             <xsl:if test="..!=/">.</xsl:if>
             <xsl:value-of select="@name"/>
         </xsl:if>
     </xsl:template>
