You have recursion.... :-)

This template get's a filename and gives back the directory part of
it. Giving back the filename part is achieved along the same line

You call it somehow like

<xsl:call-template name="strip">
<xsl:with-param name="relfile">foo/bar/baz.xml</xsl:with-param>
</xsl:call-template>



  <xsl:template name="strip">
    <xsl:param name="reldir"/>
    <xsl:param name="relfile"/>
    <xsl:choose>
      <xsl:when test="contains($relfile, '/')">
      <xsl:call-template name="strip">
        <xsl:with-param name="relfile">
          <xsl:value-of select="substring-after($relfile,'/')"/>
        </xsl:with-param>
        <xsl:with-param name="reldir">
          <xsl:value-of select="concat($reldir, substring-before($relfile,'/'), '/')"/>
        </xsl:with-param>
      </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$reldir"/>    
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
