Question

我在这里遇到一些问题，递归运行总计不会为我的xsl模板加起来是我的xsl和xml的代码

XML：

 </xsl:for-each-group>
          Subtotal:
          <td>
          <xsl:for-each-group select="current-group()" group by="@ItemNumber">
           <xsl:sort select="current-grouping-key()"/>
            <xsl:call-template name="count_subtotal">
            <xsl:with-param name="cur_grp_qty" select="sum(current-group()/Quantity)"/>
             <xsl:with-param name="cur_grp_up" select="distinct-values(current-group()/UnitPrice)"/>
             </xsl:call-template>
              </xsl:for-each-group>
  </xsl:for-each-group>


<xsl:template name="count_subtotal">
      <xsl:param name="total" select="0"/>
      <xsl:param name="cur_grp_qty"/>
      <xsl:param name="cur_grp_up"/>
      <xsl:choose>
         <xsl:when test="$cur_grp_qty">
            <xsl:variable name="first_total" select="$cur_grp_qty[1]*$cur_grp_up[1]"/>
            <xsl:call-template name="count_subtotal">
               <xsl:with-param name="cur_grp_qty" select="$cur_grp_qty[position() &gt; 1]"/>
               <xsl:with-param name="total" select="$first_total+$total"/>
            </xsl:call-template>
         </xsl:when>
         <xsl:otherwise>
            <xsl:value-of select="round($total)"/>
         </xsl:otherwise>
      </xsl:choose>
   </xsl:template>

这是XML文件：

<Items>
    <Item ItemNumber="1">
        <ProductName>c</ProductName>
        <ProviderName>c</ProviderName>
        <Quantity>2</Quantity>
        <UnitPrice>39</UnitPrice>
    </Item>
    <Item ItemNumber="2">
        <ProductName>b</ProductName>
        <ProviderName>b</ProviderName>
        <Quantity>1</Quantity>
        <UnitPrice>3</UnitPrice>
      </Item>
      <Item ItemNumber="3">
        <ProductName>abt</ProductName>
        <ProviderName>bd</ProviderName>
        <Quantity>1</Quantity>
        <UnitPrice>12</UnitPrice>
      </Item>
      <Item ItemNumber="4">
        <ProductName>a</ProductName>
        <ProviderName>a</ProviderName>
        <Quantity>1</Quantity>
        <UnitPrice>3</UnitPrice>
      </Item>
      <Item ItemNumber="5">
        <ProductName>ab</ProductName>
        <ProviderName>cd</ProviderName>
        <Quantity>2</Quantity>
        <UnitPrice>1</UnitPrice>
      </Item>
      <Item ItemNumber="6">
        <ProductName>sdf</ProductName>
        <ProviderName>bfd</ProviderName>
        <Quantity>1</Quantity>
        <UnitPrice>12</UnitPrice>
      </Item>

欲望html页面是这样的：

无论如何，我已经创建了新的XSLT来生成输出。看看：

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

  <xsl:output indent="yes"/>

  <xsl:template match="/">
    <html>
      <head/>
      <body>
        <table>
          <thead>
            <tr>
              <th>
                <xsl:text>Item Number</xsl:text>
              </th>
              <th>
                <xsl:text>Quantity</xsl:text>
              </th>
              <th>
                <xsl:text>Unit Price</xsl:text>
              </th>
              <th>
                <xsl:text>Total</xsl:text>
              </th>
            </tr>
          </thead>
          <tbody>
            <xsl:for-each select="//Item">
              <tr>
                <td>
                  <xsl:value-of select="ProductName"/>
                </td>
                <td>
                  <xsl:value-of select="Quantity"/>
                </td>
                <td>
                  <xsl:value-of select="UnitPrice"/>
                </td>
                <td>
                  <xsl:value-of select="sum(Quantity * UnitPrice)"/>
                </td>
              </tr>
            </xsl:for-each>
            <tr colspan="3">
              <xsl:value-of select="sum(for $x in //Item return ($x/Quantity * $x/UnitPrice))"/>
            </tr>
          </tbody>
        </table>
      </body>
    </html>
  </xsl:template>

</xsl:stylesheet>

可以使用FXSL的scanl模板/功能 - 如下所示：Is it possible to keep a count in a for-each loop in xslt
