執行「集團通過」用SUM函數在XSLT 1.0

Question

我要像下表組織了一個結果：

**Costc 1000**   
    Product code Quantity Total amount 

    SALESCOST  1 120.04 
    LEASINGRENT  1 59.90 

**Costc 2000**   
    Product code Quantity Total amount 

    SALESCOST  1 118.94 
    LEASINGCOST  1 513.34 

**Costc 3000**   
    Product code Quantity Total amount 

    LEASINGCOST  1 658.24 
    LEASINGRENT  2 100.80 

和輸入文件我有這個樣子。

<?xml version="1.0" encoding="iso-8859-1"?>

如何才能做到這一點？ 它的多級組合由此也算和計數函數，對我來說太複雜了。 非常感謝

Answer 1

在XSLT 1.0，您將需要使用一種稱爲Meunchian分組技術。在這種情況下，您首先按Costc元素分組，然後按產品元素。

這意味着您需要定義兩個鍵。首先通過到組的詳細信息COSTC

<xsl:key name="costc" match="Detail" use="Costc/Value"/> 

然後通過到組的詳細信息COSTC和產品

<xsl:key name="product" match="Detail" use="concat(Costc/Value, '|', Products/ProductCode)"/> 

（請注意使用的串聯管道符，它是重要的是這個字符不會出現在數值或產品代碼中）。

然後，由COSTC元素組，你可以做到以下幾點：

<xsl:apply-templates 
    select="Detail[generate-id() = generate-id(key('costc', Costc/Value)[1])]"> 

這將讓你第一詳細元素爲每一個獨特COSTC元素。然後，對於每個這樣的組，然後您將根據該組內的產品進行分組。

<xsl:apply-templates 
    select="../Detail 
     [Costc/Value = current()/Costc/Value] 
     [generate-id() 
     = generate-id(key('product', concat(Costc/Value, '|', Products/ProductCode))[1])]" /> 

因此，考慮到下面的XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output method="html" indent="yes"/> 

    <xsl:key name="costc" match="Detail" use="Costc/Value"/> 
    <xsl:key name="product" match="Detail" use="concat(Costc/Value, '|', Products/ProductCode)"/> 

    <xsl:template match="/Details"> 
     <xsl:apply-templates select="Detail[generate-id() = generate-id(key('costc', Costc/Value)[1])]" mode="Cost"> 
     <xsl:sort select="Costc/Value" /> 
     </xsl:apply-templates> 
    </xsl:template> 

    <xsl:template match="Detail" mode="Cost"> 
     <h1><xsl:value-of select="Costc/Value" /></h1> 
     <table> 
     <tr> 
      <td>Product Code</td> 
      <td>Quantity</td> 
      <td>Total amount</td> 
     </tr> 
     <xsl:apply-templates select="../Detail[Costc/Value = current()/Costc/Value][generate-id() = generate-id(key('product', concat(Costc/Value, '|', Products/ProductCode))[1])]" mode="Product" /> 
     </table> 
    </xsl:template> 

    <xsl:template match="Detail" mode="Product"> 
     <tr> 
      <td><xsl:value-of select="Products/ProductCode" /></td> 
      <td><xsl:value-of select="sum(key('product', concat(Costc/Value, '|', Products/ProductCode))//Quantity)" /></td> 
      <td><xsl:value-of select="sum(key('product', concat(Costc/Value, '|', Products/ProductCode))/TotAmount)" /></td> 
     </tr> 
    </xsl:template> 
</xsl:stylesheet> 

當適用於您的示例XML，下面是輸出：

<h1>1000</h1> 
<table> 
    <tr> 
     <td>Product Code</td> 
     <td>Quantity</td> 
     <td>Total amount</td> 
    </tr> 
    <tr> 
     <td>SALESCOST</td> 
     <td>1</td> 
     <td>120.04</td> 
    </tr> 
    <tr> 
     <td>LEASINGRENT</td> 
     <td>1</td> 
     <td>59.9</td> 
    </tr> 
</table> 
<h1>2000</h1> 
<table> 
    <tr> 
     <td>Product Code</td> 
     <td>Quantity</td> 
     <td>Total amount</td> 
    </tr> 
    <tr> 
     <td>SALESCOST</td> 
     <td>1</td> 
     <td>118.94</td> 
    </tr> 
    <tr> 
     <td>LEASINGCOST</td> 
     <td>1</td> 
     <td>513.34</td> 
    </tr> 
</table> 
<h1>3000</h1> 
<table> 
    <tr> 
     <td>Product Code</td> 
     <td>Quantity</td> 
     <td>Total amount</td> 
    </tr> 
    <tr> 
     <td>LEASINGCOST</td> 
     <td>1</td> 
     <td>658.24</td> 
    </tr> 
    <tr> 
     <td>LEASINGRENT</td> 
     <td>2</td> 
     <td>100.8</td> 
    </tr> 
</table> 

Answer 2

這個怎麼樣？

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" > 
    <xsl:output method="text"/> 

    <xsl:template match="/"> 
     <xsl:for-each-group select="*/Detail" group-by="Costc/Value" > 
      <xsl:sort select="current-grouping-key()" order="ascending"/> 

      <xsl:value-of select="concat('** Costc ',current-grouping-key())"/> 
      <xsl:text>&#xD;&#xA; Product code Quantity Total amount&#xD;&#xA;</xsl:text> 

      <xsl:for-each-group select="current-group()" group-by="Products/ProductCode" > 
       <xsl:text> </xsl:text>    
       <xsl:value-of select="current-grouping-key()"/> 
       <xsl:text> </xsl:text> 
       <xsl:value-of select="number(sum(current-group()/Quantity, current-group()/Products/Quantity))" />    
       <xsl:text> </xsl:text> 
           <xsl:value-of select="sum(current-group()/TotAmount)" />     
       <xsl:text>&#xD;&#xA;</xsl:text>    
      </xsl:for-each-group>  

      <xsl:text>&#xD;&#xA;</xsl:text> 

     </xsl:for-each-group> 
    </xsl:template> 
</xsl:stylesheet> 

你將不得不調整格式。這個XSLT只提供算法。 這是我的輸出：

** Costc 1000 
    Product code Quantity Total amount 
    SALESCOST 1 120.04 
    LEASINGRENT 1 59.9 

** Costc 2000 
    Product code Quantity Total amount 
    SALESCOST 1 118.94 
    LEASINGCOST 1 513.34 

** Costc 3000 
    Product code Quantity Total amount 
    LEASINGCOST 1 658.24 
    LEASINGRENT 2 100.8
