如何将xsl的计算结果放在新元素中

标签： xml xslt

我使用xsl来计算每个元素“Basisproduct”的累计总数。 输出最终放在同一个xml中，在“Totals”之后的一些新元素中，如下所示：

<Totals>
 <Totalproduct>
    <Basisproduct>110</Basisproduct>
    <Cumul_Amount>1,52</CustInvoice_LineAmount>
  </Totalproduct>
 <Totalproduct>
    <Basisproduct>198</Basisproduct>
    <Cumul_Amount>294,77</CustInvoice_LineAmount>
  </Totalproduct>
 <Totalproduct>
    <Basisproduct>992</Basisproduct>
    <Cumul_Amount>163,32</CustInvoice_LineAmount>
  </Totalproduct>
 <Totalproduct>
    <Basisproduct>993</Basisproduct>
    <Cumul_Amount>193,78</CustInvoice_LineAmount>
  </Totalproduct>
<Totals>

<-----I have this xml as an input.------>

<?xml version="1.0" encoding="utf-8"?>
<Report Name="SalesInvoice">
    <ReportName>SalesInvoice</ReportName>
  <Invoice>
    <InvoicingName>Test Company</InvoicingName>
  </Invoice>
  <ConditionalArea>
      <BodyCustInvoice>
        <Basisproduct>110</Basisproduct>
        <CustInvoice_LineAmount>1,52</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>198</Basisproduct>
        <CustInvoice_LineAmount>20,11</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>198</Basisproduct>
        <CustInvoice_LineAmount>20,22</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>992</Basisproduct>
        <CustInvoice_LineAmount>3033</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>993</Basisproduct>
        <CustInvoice_LineAmount>30,34</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>992</Basisproduct>
        <CustInvoice_LineAmount>30,35</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>992</Basisproduct>
        <CustInvoice_LineAmount>30.45</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>993</Basisproduct>
        <CustInvoice_LineAmount>30,46</CustInvoice_LineAmount>
      </BodyCustInvoice>
      <BodyCustInvoice>
        <Basisproduct>198</Basisproduct>
        <CustInvoice_LineAmount>100.99</CustInvoice_LineAmount>
      </BodyCustInvoice>,      </ConditionalArea>
  <Totals>
  </Totals>
</Report>

我用来计算“Basisproduct”的累积和的xsl是：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">              <xsl:output indent="yes"/>       <xsl:strip-space elements="*"/>

<xsl:decimal-format name="EU" decimal-separator="," grouping-separator="."/>

<xsl:key name="KType" match="Basisproduct" use="."/>
    <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
   </xsl:template>

    <xsl:template match="TotalSBasis">
     <TotalSBasis>
       <xsl:for-each select="/*/*/*/Basisproduct [generate-id() = generate-id(key  ('KType', .)[1])]">
         <xsl:variable name="currProd" select="."/>
         <Totalproduct>
           <xsl:copy-of select="."/>
           <Cumul_Amount>
             <xsl:value-of select="sum(/*/*/BodyCustInvoiceTrans  [Basisproduct=$currProd]/CustInvoiceTrans_LineAmount)"/>
           </Cumul_Amount>
         </Totalproduct>
       </xsl:for-each>
           </TotalSBasis>
   </xsl:template>
  </xsl:stylesheet>

<Totals>
  <xsl:for-each select="*/*/*/Basisproduct [generate-id() = generate-id(key  ('KType', .)[1])]">
    <Totalproduct>
      <Basisproduct><xsl:value-of select= "."/></Basisproduct>
      <Cumul_Amount>
        <xsl:value-of select= "/*/*/*[Basisproduct = current()][last()]/CustInvoice_LineAmount + sum(/*/*/*[Basisproduct = current()][last()]/preceding-sibling::*/CustInvoice_LineAmount)"/>
      </Cumul_Amount>
    </Totalproduct>
  </xsl:for-each>
</Totals>

这将以所提及的结果输出xml，并显示您显示的结果。

编辑：更新了我的XSLT，以适应OP的请求，将总数插入原始XML。解决问题的诀窍是使用身份模板和全局变量。

如果您使用此XSLT：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="KType" match="Basisproduct" use="."/>
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

    <!-- create a variable w/ the calculated totals -->
    <xsl:variable name="CalculatedTotals">
        <xsl:for-each select="*/*/*/Basisproduct [generate-id() = generate-id(key  ('KType', .)[1])]">
            <xsl:element name="TotalProduct">
                <xsl:element name="Basisproduct">
                    <xsl:value-of select= "."/>
                </xsl:element>
                <xsl:element name="Cumul_Amount">
                    <xsl:value-of select= "/*/*/*[Basisproduct = current()][last()]/CustInvoice_LineAmount + sum(/*/*/*[Basisproduct = current()][last()]/preceding-sibling::*/CustInvoice_LineAmount)"/>
                </xsl:element>
            </xsl:element>
        </xsl:for-each>
    </xsl:variable>

    <!-- identity -->
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <!-- root -->
    <xsl:template match="/">
        <xsl:apply-templates select="node()|@*"/>
    </xsl:template>    

    <xsl:template match="Totals">
        <xsl:copy>
            <!-- insert the calculated totals -->
            <xsl:copy-of select="$CalculatedTotals"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

您将获得此XML输出：

   </Totals>
</Report>

在Win 7上使用Oxygen 12测试。

您应该做的是使用身份转换，然后覆盖Totals元素。

编辑：根据OP在@james.garriss回答中的评论，我将计算修改为仅对所有内容求和。

输入XML 

<Report Name="SalesInvoice">
  <ReportName>SalesInvoice</ReportName>
  <Invoice>
    <InvoicingName>Test Company</InvoicingName>
  </Invoice>
  <ConditionalArea>
    <BodyCustInvoice>
      <Basisproduct>110</Basisproduct>
      <CustInvoice_LineAmount>1.52</CustInvoice_LineAmount>
    </BodyCustInvoice>
    <BodyCustInvoice>
      <Basisproduct>198</Basisproduct>
      <CustInvoice_LineAmount>20.11</CustInvoice_LineAmount>
    </BodyCustInvoice>
    <BodyCustInvoice>
      <Basisproduct>198</Basisproduct>
      <CustInvoice_LineAmount>20.22</CustInvoice_LineAmount>

      <CustInvoice_LineAmount>100.99</CustInvoice_LineAmount>
    </BodyCustInvoice>
  </ConditionalArea>
  <Totals> </Totals>
</Report>

XSLT样式表 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:strip-space elements="*"/>

  <xsl:template match="node()|@*">

    </xsl:copy>
  </xsl:template>

  <xsl:template match="Totals">

输出XML （使用Xalan :-(）

此变换按Basisproduct对元素进行分组，并计算每个组的总和。请注意，它包含identity.xsl众所周知的Identity Transformation。

[XSLT 1.0] 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:include href="identity.xsl"/>

    <xsl:key name="KType" match="BodyCustInvoice" use="Basisproduct"/>

    <xsl:template match="Totals">
        <Totals>
            <xsl:apply-templates select="
                preceding-sibling::ConditionalArea[1]/BodyCustInvoice
                [generate-id() 
                = generate-id(key  ('KType', Basisproduct)[1])]" mode="totals"/>
        </Totals>
    </xsl:template>

    <xsl:template match="BodyCustInvoice" mode="totals">
        <Totalproduct>
            <Basisproduct><xsl:value-of select="Basisproduct"/></Basisproduct>
            <Cumul_Amount>  
                <xsl:value-of select="
                    sum(key('KType',Basisproduct)/CustInvoice_LineAmount)"/>
            </Cumul_Amount>
        </Totalproduct>
    </xsl:template>
