xslt 1.0更新正確的標頭

下面給出了請求XML，並給出了我正在使用的XSLT轉換。xslt 1.0更新正確的標頭

不幸的是ordertotal元素在轉換後重復兩次。 如何更新ordertotal元素而不是重複它？

請求XML是

XSLT是

<xsl:output method="xml" indent="yes" /> 

<xsl:template match="*|@*"> 
    <xsl:copy> 
     <xsl:apply-templates select="*|@*" /> 
    </xsl:copy> 
</xsl:template> 

<xsl:template match="return"> 
    <xsl:copy> 
     <xsl:copy-of select="@*|*" /> 
     <ordertotal><xsl:call-template name="calculate-total" /></ordertotal> 
    </xsl:copy> 
</xsl:template> 

<!-- Recursive template --> 
<xsl:template name="calculate-total"> 
    <!-- Select by default the set of orderDetails from the current context --> 
    <xsl:param name="orderDetails" 
       select="orderDetails" /> 
    <!-- Param which is going to keep track of the result step by step --> 
    <xsl:param name="total" 
       select="'0'" /> 

    <xsl:choose> 
     <!-- If we have remaining order details, recurse --> 
     <xsl:when test="$orderDetails"> 
      <xsl:call-template name="calculate-total"> 
       <!-- Remove the current element for the next step --> 
       <xsl:with-param name="orderDetails" 
           select="$orderDetails[position() > 1]" /> 
       <!-- Do the partial operation for the current element, and continue to the next step --> 
       <xsl:with-param name="total" 
           select="$total + ($orderDetails[1]/itemPrice * $orderDetails[1]/itemQty)" /> 
      </xsl:call-template>   
     </xsl:when> 
     <!-- Output the result --> 
     <xsl:otherwise> 
      <xsl:value-of select="$total" /> 
     </xsl:otherwise> 
    </xsl:choose> 

</xsl:template>

我已經看到了他們兩人之間的差異，但下一次我認爲最好把所有事情都放在一個問題上。他們太相似了...... – 2013-02-18 12:11:05

不知道爲什麼突然之間這個老問題被拒絕投了 – Joe2013 2013-03-12 04:48:21

@downvoter - 這個問題出了什麼問題。 – Joe2013 2013-03-12 08:46:36

你必須遵循從你這裏張貼的問題同樣的想法：XSLT - Updating the Header

而是匹配結果，匹配的OrderTotal和改變XPath表達式來選擇 ORDERDETAILS元素。

因此，改變這種：

<xsl:template match="return"> 
    <xsl:copy> 
     <xsl:copy-of select="@*|*" /> 
     <ordertotal><xsl:call-template name="calculate-total" /></ordertotal> 
    </xsl:copy> 
</xsl:template>

要：

<xsl:template match="ordertotal"> 
    <xsl:copy> 
     <xsl:call-template name="calculate-total"> 
      <xsl:with-param name="orderDetails" 
          select="../orderDetails" /> 
     </xsl:call-template> 
    </xsl:copy> 
</xsl:template>

然後你可以從計算，總模板中刪除默認值第一個參數，除去選擇=「訂單明細」屬性。

此外，因爲您沒有使用元素複製的，您必須將身份模板更改爲：

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

所以完整的樣式表是：

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

    <xsl:output method="xml" indent="yes" /> 

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

    <xsl:template match="ordertotal"> 
     <xsl:copy> 
      <xsl:call-template name="calculate-total"> 
       <xsl:with-param name="orderDetails" 
           select="../orderDetails" /> 
      </xsl:call-template> 
     </xsl:copy> 
    </xsl:template> 

    <xsl:template name="calculate-total"> 
     <xsl:param name="orderDetails" /> 
     <xsl:param name="total" 
        select="'0'" /> 

     <xsl:choose> 
      <xsl:when test="$orderDetails"> 
       <xsl:call-template name="calculate-total"> 
        <xsl:with-param name="orderDetails" 
            select="$orderDetails[position() > 1]" /> 
        <xsl:with-param name="total" 
            select="$total + ($orderDetails[1]/itemPrice * $orderDetails[1]/itemQty)" /> 
       </xsl:call-template>   
      </xsl:when> 
      <xsl:otherwise> 
       <xsl:value-of select="$total" /> 
      </xsl:otherwise> 
     </xsl:choose> 
    </xsl:template> 

</xsl:stylesheet>
