Ok. Here where I am. Now I have to sort each tag using the 'number'.

<xsl:variable name="tagList">
 <tags>
  <xsl:for-each select="//data/items/item[ @isVisible = '1' ]">
   <xsl:variable name="itemPosition" select="position()" />
   <xsl:variable name="item" select="//data/items/item[ $itemPosition 
]" />

   <xsl:for-each select="$item/tags/tag">
    <xsl:variable name="tagPosition" select="position()" />
    <xsl:variable name="tag" select="
      //data/items/item[ $itemPosition ]/tags/tag [ $tagPosition ]" />

    <xsl:variable name="number" select="count(
      //data/items/item[ @isVisible = '1' ]/tags/tag [ $tag = . ] )" />

    <xsl:choose>
     <xsl:when test="$number = 1">
      <tag>
       <xsl:attribute name="number">
        <xsl:value-of select="$number" />
       </xsl:attribute>
       <xsl:value-of select="$tag" />
      </tag>
     </xsl:when>
     <xsl:otherwise>
      <xsl:variable name="isFound">
      <xsl:for-each select="//data/items/item[ @isVisible = '1' and
        position() &gt; $itemPosition ]">

       <xsl:variable name="tmpPosition" select="position()" />
       <xsl:variable name="tmpItem" select="
         //data/items/item[ $tmpPosition ]" />

       <xsl:for-each select="$tmpItem/tags/tag">
        <xsl:variable name="tmpTagPosition" select="position()" />
        <xsl:variable name="tmpTag" select="//data/items/
          item[ $itemPosition ]/tags/tag [ $tmpTagPosition ]" />

         <xsl:if test="$tmpTag = $tag">
          <xsl:value-of select="1" />
         </xsl:if>
        </xsl:for-each>
       </xsl:for-each>
      </xsl:variable>
      <xsl:if test="$isFound != 1">
       <tag>
        <xsl:attribute name="number">
         <xsl:value-of select="$number" />
        </xsl:attribute>
        <xsl:value-of select="$tag" />
       </tag>
      </xsl:if>
     </xsl:otherwise>
    </xsl:choose>
   </xsl:for-each>
  </xsl:for-each>
 </tags>
</xsl:variable>
