xsl - 每隔一個div包含每個2項目

Question

我有一個xsl：for-each，我想將每2個項目包裝在一個div中。怎麼做？

<xsl:for-each select="$datapath/PackageInfoList/PackageInfo"> 

<!-- lots of html in here --> 

</xsl:for-each> 

所以結果將是：

<div> 
<!-- lots of html in here --> 
<!-- lots of html in here --> 
</div> 
<div> 
<!-- lots of html in here --> 
<!-- lots of html in here --> 
</div> 

Answer 1

選擇奇數<PackageInfo>元件，這樣

<xsl:for-each select="$datapath/PackageInfoList/PackageInfo[position() mod 2 = 1]"> 
    <div> 
    <!-- lots of html in here --> 

    <!-- do something with following-sibling::PackageInfo[1] --> 
    </div> 
</xsl:for-each> 

這在位置1，3，5等處理運行的元件手動分別首先執行<PackageInfo>。

更地道

<xsl:template match="/"> 
    <xsl:apply-templates select="$datapath/PackageInfoList/PackageInfo" mode="group2" /> 
</xsl:template> 

<xsl:template match="PackageInfo" mode="group2"> 
    <xsl:if test="position() mod 2 = 1"> 
    <div> 
     <xsl:apply-templates select=". | following-sibling::PackageInfo[1]" /> 
    </div> 
    </xsl:if> 
</xsl:template> 

<xsl:template match="PackageInfo"> 
    <!-- lots of html in here --> 
</xsl:template> 

更靈活

<xsl:template match="/"> 
    <xsl:apply-templates select="$datapath/PackageInfoList/PackageInfo" mode="group"> 
    <xsl:with-param name="groupcount" select="2" /> 
    </xsl:apply-templates> 
</xsl:template> 

<xsl:template match="PackageInfo" mode="group"> 
    <xsl:param name="groupcount" select="2" /> 

    <xsl:if test="position() mod $groupcount = 1"> 
    <div> 
     <xsl:apply-templates select=". | following-sibling::PackageInfo[position() &lt; $groupcount]" /> 
    </div> 
    </xsl:if> 
</xsl:template> 

<xsl:template match="PackageInfo"> 
    <!-- lots of html in here --> 
</xsl:template>
