XSLT 1.0 带键的多级分组答案

【问题标题】：XSLT 1.0 Multi-Level Grouping with KeysXSLT 1.0 带键的多级分组
【发布时间】：2016-04-13 14:39:09
【问题描述】：

我正在尝试从 AWS 分配文件生成报告。我已将适当的数据从 CSV 转换为 XML，但无法完全弄清楚如何在 XSLT 1.0 (.net) 中进行键/分组

这是 XML 文件。

我想要做的是在业务部门级别的第一个我想要每个 ProductName 的 UsageQuantity 和 TotalCost 的总和。

然后对每个办公室和工作执行相同的操作。工作不会很难，也不需要分组。

我正在将其输出到 HTML。

对于 BusinessUnit，我尝试了几个关键配置，但似乎都没有像我预期的那样工作。

我已经尝试过（仅限 BusinessUnit 级别）：

不是我想要的。相同的产品名称应该加在一起。

标签： xml xslt xslt-1.0 grouping

【解决方案1】：

如果您可以将 xml 和 xslt 减少到问题部分，那么提供帮助会容易得多。但无论如何，这里有一些改变建议。

海岸产品的关键

<xsl:key name="kProduct" 
    match="Cost" 
    use="concat(ancestor::BusinessUnit/Name, '#', ProductName)"/>

BusinessUnit 中产品组的循环

 <xsl:variable name="bu" select="." />
 <xsl:for-each 
            select="Office/Job/Costs/Cost[
            count(. | key('kProduct',concat($bu/Name, '#', ProductName))[1]) = 1]">

本组内的费用

<xsl:variable name="this_pg" select="." />
<xsl:variable name="this_pgm" 
        select="key('kProduct',concat($bu/Name, '#', $this_pg/ProductName))" />

然后用这个来求和：

 <xsl:value-of select="format-number(sum($this_pgm/UsageQuantity),'##,##0.00')"/>

会是这样的：

<xsl:template match="BusinessUnit">

   <!-- .. table head -->
        <xsl:variable name="bu" select="." />
        <xsl:for-each 
            select="Office/Job/Costs/Cost[
            count(. | key('kProduct',concat($bu/Name, '#', ProductName))[1]) = 1]">
           <xsl:variable name="this_pg" select="." />
           <xsl:variable name="this_pgm" 
                  select="key('kProduct',concat($bu/Name, '#', $this_pg/ProductName))" />
            <tr>
                <th class="rowHeader">
                    <xsl:value-of select="ProductName"/>
                </th>
                <td class="num">
                    <xsl:value-of select="format-number(sum($this_pgm/UsageQuantity),'##,##0.00')"/>
