XSLT para cada ciclo em XML simples

tenho um XML como este

      <filters extra="filters">
<ISP_WebItem FILTER="Farve" FILTERNAME="Sort" UNITCODE=""/>
<ISP_WebItem FILTER="Længde" FILTERNAME="51" UNITCODE="cm"/>
<ISP_WebItem FILTER="Højde" FILTERNAME="3.2" UNITCODE="cm"/>
<ISP_WebItem FILTER="Dybde" FILTERNAME="9" UNITCODE="cm"/>
<ISP_WebItem FILTER="Stavlængde" FILTERNAME="11" UNITCODE="cm"/>
      </filters>

quero fazer um loop através de cada Isp_ Webitem e mostrar o filtro,o nome do ficheiro e o código unitário. já tentei uma coisa destas.

<xsl:for-each select="filters/ISP_WebItem ">              
          <xsl:value-of  select="FILTER" />
          <xsl:value-of  select="FILTERNAME" />
          <xsl:value-of  select="UNITCODE" />
 </xsl:for-each>

mas sem utilidade. e quando coloquei um ponto de ruptura e verifiquei, descobri que a execução de código não acontece dentro de cada laço( ponto de ruptura dentro de cada laço nunca bate).

Nota: Como algumas pessoas solicitaram para XSLT e XML completos, estou a publicá-lo aqui

<xsl:template match="/">      
<xsl:variable name="p">
  <xsl:choose>
    <xsl:when test="library:Request('pid') != ''">
      <xsl:copy-of select="shop:GetProductFromId(library:Request('pid'))" />
    </xsl:when>
    <xsl:otherwise>
      <xsl:copy-of  select="shop:GetProductFromId(shop:UrlInformation()//productid)" />
    </xsl:otherwise>
  </xsl:choose>
</xsl:variable>
<xsl:copy-of select="msxsl:node-set($p)/product/filters"/>
<xsl:for-each select="msxsl:node-set($p)/product/filters/ISP_WebItem">
    <xsl:value-of  select="@FILTER" />
    <xsl:value-of  select="@FILTERNAME" />
    <xsl:value-of  select="@UNITCODE" />
  </xsl:for-each>
</xsl:template>
