XSLT For-Each包装div中的每个第n项

Question

我有一系列节点,它们是父节点的直接子节点,我想在这些节点上循环,但是将它们包含在4个"组"中...我可能没有非常清楚地写这个,所以这可能会有所帮助;

<span class="child01">@nodename</span>
<span class="child02">@nodename</span>
<span class="child03">@nodename</span>
<span class="child04">@nodename</span>
<span class="child05">@nodename</span>
<span class="child06">@nodename</span>
<span class="child07">@nodename</span>
<span class="child08">@nodename</span>
..
<span class="child32">@nodename</span>
<span class="child33">@nodename</span>
..and so on

目标

<div class="group">
<span class="child01">@nodename</span>
<span class="child02">@nodename</span>
<span class="child03">@nodename</span>
<span class="child04">@nodename</span>
</div>
<div class="group">
<span class="child05">@nodename</span>
<span class="child06">@nodename</span>
<span class="child07">@nodename</span>
<span class="child08">@nodename</span>
</div>
<div class="group">
..
<span class="child32">@nodename</span>
</div>
<div class="group">
<span class="child33">@nodename</span>
..and so on

我尝试过这个想法的变体 - 将数据包装在开放和关闭组标签中,每隔四个循环放入一个新的关闭/打开对

<div class="group">
<xsl:for-each select="$currentPage/*">

<span>
<xsl:value-of select="@nodeName" />
</span>

 <!--
            =============================================================
            After very 4th item  
            =============================================================
            -->
            <xsl:if test="position() mod 4 = 0">
              <xsl:text></div><div class="page"></xsl:text>
            </xsl:if>

        </xsl:for-each>
</div>

但基本上似乎XSLT不会让我从关闭无法匹配的标签开始到目前为止我发现的clkoset解决方案是jquery中的'修复' 包围每三个div的div但我宁愿不依赖于javascript来格式化页面.

这种转变:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:param name="pNumCols" select="3"/>

 <xsl:template match="/*">
  <xsl:apply-templates select="span[position() mod $pNumCols = 1]"/>
 </xsl:template>

 <xsl:template match="span">
  <div>
   <xsl:copy-of select=
    ".|following-sibling::span[not(position() > $pNumCols -1)]"/>
  </div>
 </xsl:template>
</xsl:stylesheet>

当应用于提供的XML文档时:

<t>
    <span class="child01">@nodename</span>
    <span class="child02">@nodename</span>
    <span class="child03">@nodename</span>
    <span class="child04">@nodename</span>
    <span class="child05">@nodename</span>
    <span class="child06">@nodename</span>
    <span class="child07">@nodename</span>
    <span class="child08">@nodename</span> .. 
    <span class="child32">@nodename</span>
    <span class="child33">@nodename</span>
</t>

产生想要的结果:

<div>
   <span class="child01">@nodename</span>
   <span class="child02">@nodename</span>
   <span class="child03">@nodename</span>
</div>
<div>
   <span class="child04">@nodename</span>
   <span class="child05">@nodename</span>
   <span class="child06">@nodename</span>
</div>
<div>
   <span class="child07">@nodename</span>
   <span class="child08">@nodename</span>
   <span class="child32">@nodename</span>
</div>
<div>
   <span class="child33">@nodename</span>
</div>
