Re: [xsl] Retrieving Full XPATH expression

["Robert Koberg" <rob@xxxxxxxxxx>]

An easier way to do what I think you are trying to do is:


<xsl:template match="folder" mode="current-path-builder">

      <xsl:apply-templates select="parent::folder"
mode="current-path-builder"/>
      <xsl:value-of select="@name"/>
      <xsl:text>/</xsl:text>

</xsl:template>
