我需要通过添加嵌套文件夹的最后一个单元格来计算总和。 FOLDER1而不是23美元它应该有23 + 11 + 44，FOLDER2应该有11 + 44和FOLDER3只有44，因为那里没有嵌套行。

预期输出为：

Answer 1

将以下模板添加到样式表中，以便从当前XML输入中生成所需的结果。

<xsl:template match="cell[@sum]" priority="1.5">
    <td>
        <div>
            <xsl:call-template name="sum">
                <xsl:with-param name="currentRow" select=".." />
            </xsl:call-template>
        </div>
    </td>  
</xsl:template>

<xsl:template name="sum">
    <xsl:param name="currentRow" />
    <xsl:param name="sum" select="0"/>
    <xsl:choose>
        <xsl:when test="$currentRow//cell[@sum]">
            <xsl:call-template name="sum">
                <xsl:with-param name="currentRow" 
                                select="($currentRow//row[cell[@sum]])[1]" />
                <xsl:with-param name="sum" 
                                select="$sum+
                                        number(
                                          translate(
                                            $currentRow/cell[@sum], 
                                            '$',
                                            ''))"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:text>$</xsl:text>
            <xsl:value-of select="$sum"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

Answer 2

实现所需总和的一种方法是从您拥有的样式表开始，并进行以下更改......

这样做......

如果可能，请从输入文档中删除“$”字符。 XML主要关注数据和语义，而不是表示，因此最好省略表示字符。但是，如果无法做到这一点，请告诉我们。我可以制作一个替代解决方案，使用输入文档，使用$ sign，但它会更复杂。

只需添加以下模板......

<xsl:template match="cell[@sum]" priority="1.5">
  <!-- Summation columns -->
  <td>
     <div>
      <xsl:call-template name="style">
        <xsl:with-param name="margin" select="20" />
       </xsl:call-template>
       <xsl:value-of select="concat( '$', sum( ../descendant-or-self::row/cell[@sum]))" />
     </div>
  </td>  
</xsl:template>

注意事项

此解决方案依赖于以下假设。如果这些假设中的任何一个是错误的，请通知我，我将相应调整解决方案。

每个可汇总行中的一个单元格具有属性和。这些包含要添加的值。
可汇总单元格的内容只包含一个数字。它不包括任何演示文字字符，例如'$'

计算并显示嵌套元素XSLT的总和

2 个答案:

这样做......
