在分组父元素内对子元素进行分组XSLT

我正在使用for-each-group组合使用for-each-group的XML元素，并且我遇到的问题是这些XML元素的子元素具有自己的子元素。我也想结合儿童元素。在分组父元素内对子元素进行分组XSLT

我输入XML看起来是这样的：

<Root> 
    <Header> 
    </Header> 
    <Summary ID="1"> 
     <ID>1</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Net_Sales_Amount>340.00</Net_Sales_Amount> 
     <DATA_From_2> 
     <Sales_Amount>340.00</_Sales_Amount> 
     </DATA_From_2> 
    </Summary> 
    <Summary ID="1"> 
     <ID>1</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Batch_Number>04002</Batch_Number> 
     <Net_Sales_Amount>130.00</Net_Sales_Amount> 
     <DATA_From_2> 
     <Sales_Amount>130.00</Sales_Amount> 
     </DATA_From_2> 
     <DATA_From_8> 
     <Invoice_Amount>20</Invoice_Amount> 
     <Invoice_Number>123</Invoice_Number> 
     </DATA_From_8> 
     <DATA_From_8> 
     <Invoice_Amount>15</Invoice_Amount> 
     <Invoice_Number>456</Invoice_Number> 
     </DATA_From_8> 
    </Summary> 
    <Summary ID="2"> 
     <ID>2</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Net_Sales_Amount>40.00</Net_Sales_Amount> 
     <DATA_From_2> 
     <Sales_Amount>40.00</Sales_Amount> 
     </DATA_From_2> 
    </Summary> 
    <Summary ID="2"> 
     <ID>2</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Net_Sales_Amount>819.91</Net_Sales_Amount> 
     <DATA_From_2> 
     <Sales_Amount>734.91</Sales_Amount> 
     </DATA_From_2> 
     <DATA_From_5> 
     <Sales_Amount>85.00</Sales_Amount> 
     </DATA_From_5> 
    </Summary> 
</Root>

这里是我的XSLT文件。我接近我想要的输出，但不是将相同的子元素组合在一起，而是将它们全部放在Summary元素中。

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output indent="yes" /> 

    <xsl:template match="/*"> 
     <xsl:copy> 
      <Root> 
       <xsl:for-each-group select="/Root/Summary" group-by="@ID"> 
        <Summary ID="{@ID}"> 
         <!-- Copy values that are the same --> 
         <xsl:sequence select="ID, Batch_Date"/> 

         <!-- Sum the amounts --> 
         <Net_Sales_Amount> 
          <xsl:value-of select="format-number(sum(current-group()/Net_Sales_Amount), '0.00')"/> 
         </Net_Sales_Amount> 

         <!-- Combine the record types in this Summary element --> 
<!--      <xsl:sequence select="DATA_From_2, DATA_From_3, DATA_From_5, DATA_From_8"/> --> 

         <xsl:for-each-group select="current-group()" group-by="DATA_From_2"> 
          <Data_From_2> 
           <Sales_Amount> 
            <xsl:value-of select="format-number(sum(current-group()/Data_From_2/Combined_Sales_Amount), '0.00')"/> 
           </Sales_Amount> 
          </Data_From_2> 
         </xsl:for-each-group> 

         <xsl:for-each-group select="current-group()" group-by="DATA_From_8"> 
          <Data_From_8> 
           <Invoice_Amount> 
            <xsl:value-of select="format-number(sum(current-group()/Data_From_8/Invoice_Amount), '0.00')"/> 
           </Invoice_Amount> 
           <Invoice_Number> 
            <xsl:value-of select="current-group()/Data_From_8/Invoice_Number" separator=" | "/> 
           </Invoice_Number> 
          </Data_From_8> 
         </xsl:for-each-group> 
        </Summary> 
       </xsl:for-each-group> 

       <Header> 
       </Header> 
       <Footer> 
       </Footer> 
      </Root> 
     </xsl:copy> 
    </xsl:template> 
</xsl:stylesheet>

这里是我的电流输出：

<Root> 
    <Summary ID="1"> 
     <ID>1</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Net_Sales_Amount>470.00</Net_Sales_Amount> 
     <Data_From_2> 
     <Sales_Amount>0.00</Sales_Amount> 
     </Data_From_2> 
     <Data_From_2> 
     <Sales_Amount>0.00</Sales_Amount> 
     </Data_From_2> 
     <Data_From_8> 
     <Invoice_Amount>0.00</Invoice_Amount> 
     <Invoice_Number/> 
     </Data_From_8> 
     <Data_From_8> 
     <Invoice_Amount>0.00</Invoice_Amount> 
     <Invoice_Number/> 
     </Data_From_8> 
    </Summary> 
    <Summary ID="2"> 
     <ID>2</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Net_Sales_Amount>859.91</Net_Sales_Amount> 
     <Data_From_2> 
     <Sales_Amount>0.00</Sales_Amount> 
     </Data_From_2> 
     <Data_From_2> 
     <Sales_Amount>0.00</Sales_Amount> 
     </Data_From_2> 
     <Data_From_2> 
     <Sales_Amount>0.00</Sales_Amount> 
     </Data_From_2> 
    </Summary> 
</Root>

的XSLT不合并是相同的Data_From元素，它也无法正确填充值。

这是它应该是什么样子：

<Root> 
    <Summary ID="1"> 
     <ID>1</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Net_Sales_Amount>470.00</Net_Sales_Amount> 
     <Data_From_2> 
     <Sales_Amount>470.00</Sales_Amount> 
     </Data_From_2> 
     <Data_From_8> 
     <Invoice_Amount>35.00</Invoice_Amount> 
     <Invoice_Number/> 
     </Data_From_8> 
    </Summary> 
    <Summary ID="2"> 
     <ID>2</ID> 
     <Batch_Date>0228</Batch_Date> 
     <Net_Sales_Amount>859.91</Net_Sales_Amount> 
     <Data_From_2> 
     <Sales_Amount>771.91</Sales_Amount> 
     </Data_From_2> 
     <DATA_From_5> 
     <Sales_Amount>85.00</Sales_Amount> 
     </DATA_From_5> 
    </Summary> 
</Root>

的XSLT要结合相似的元素（Data_from_2，Data_from_5等），并添加了值。对于任何错别字或不正确的XML，我表示歉意，我做了很多复制和粘贴。感谢

怎么来的'<摘要MERCHANT_ID = “{@ MERCHANT_ID}”>'农产品'<摘要ID = “1”>' – vels4j

@ vels4j - 这是一个复制粘贴错误。我经历了并尝试使名字简单易懂。我现在修好了。 – RXC
