I have a horizontal two-level unordered list, with a bullet between each sub item. The list is generated by the following XSLT:

<xsl:param name="currentPage"/>
  <xsl:variable name="level" select="3"/>
  <xsl:variable name="preIDProduct" select="1085" />
  
  <xsl:template match="/">
    <div id="collectionCategory">
      <h1>
        <xsl:value-of select="$currentPage/@nodeName"/>
      </h1>
    </div>
    <div id="subNav">
      <ul>
        <xsl:for-each select="$currentPage/ancestor-or-self::* [@isDoc and @level=$level]/* [@isDoc and string(umbracoNaviHide) != '1']">
          <li>
            <a href="{umbraco.library:NiceUrl(@id)}">
              <xsl:if test="$currentPage/ancestor-or-self::*/@id = current()/@id">           
                <xsl:attribute name="class">selected</xsl:attribute>
              </xsl:if>
              <xsl:value-of select="@nodeName"/>
            </a>       
            <xsl:if test="count(./* [@isDoc and string(umbracoNaviHide) != '1']) &gt; 0">
              /
              <ul>              
                <xsl:apply-templates select="umbraco.library:GetPreValues($preIDProduct)/preValue">
                  <xsl:sort select="." data-type="text" order="ascending" />
                  <xsl:with-param name="node" select="current()" />
                </xsl:apply-templates>
              </ul>           
          </xsl:if>          
          </li>
        </xsl:for-each>
      </ul>
    </div>
  </xsl:template>

  <xsl:template match="preValue">
    <xsl:param name="node" />
    <xsl:if test="$node/*/productSubType[contains(., current())]">
      <li>
        <a>
          <xsl:attribute name="href" >
            <xsl:value-of select="umbraco.library:NiceUrl($node/@id)"/>
            <xsl:text>/?select=</xsl:text>
            <xsl:value-of select="."/>
          </xsl:attribute>
            <xsl:value-of select="."/>
        </a>
        <xsl:if test="position()!=last()">
          <xml:text disable-output-escaping="yes"> &#183; </xml:text>
        </xsl:if>
      </li>
    </xsl:if>
  </xsl:template>

I need to remove the bullet after the final item in the list. The test="position()!=last() is not working (I get a bullet on every item, including the last). I'm not sure how to do this type of test because in this particular scenario there is no for-each loop..
