如何在XSLT 2.0中显示子总计和总计?

标签: xml xslt

所以我需要像这样显示Subtotal和Grand Total:

但是我得到了这个:

这似乎与for循环有关,但我现在还不完全确定。它在每个标题下显示子总数。

我在这里做错了什么? 我已经在下面包含了我的XSL和XML代码。

XSL

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="html" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />

<xsl:template match="catalog">
<html>
  <head>
    <title>Books Catalog by Author</title>
  </head>
  <body>
    <h1>Books Catalog by Author</h1>
    <table border ="1" cellpadding ="5">
      <xsl:for-each-group select="book" group-by="author">
        <xsl:sort select="current-grouping-key()" />

        <tr bgcolor="#ef9f37">
          <td colspan="4">Author:
            <xsl:value-of select="current-grouping-key()" />
          </td>
        </tr>
        <tr>
          <td>ID</td><td>Title</td><td>Genre</td><td>Price</td>
        </tr>
        <xsl:for-each select="current-group()">
          <tr>
            <td><xsl:value-of select="@id"/></td>
            <td><xsl:value-of select="title"/></td>
            <td><xsl:value-of select="genre"/></td>
            <td><xsl:value-of select="price"/></td>
        </tr>




        </xsl:for-each>


      </xsl:for-each-group>
      <tr>
                <td colspan="3" align="right">Sub Total:</td>

        </tr>
    </table>
    </body>
  </html>
 </xsl:template>

</xsl:transform>

您可以使用sum函数简单地将节点的值与format-number相加,以将结果显示为2位小数。

试试这个XSLT

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="html" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />

<xsl:template match="catalog">
<html>
  <head>
    <title>Books Catalog by Author</title>
  </head>
  <body>
    <h1>Books Catalog by Author</h1>
    <table border ="1" cellpadding ="5">
      <xsl:for-each-group select="book" group-by="author">
        <xsl:sort select="current-grouping-key()" />
        <tr bgcolor="#ef9f37">
          <td colspan="4">Author:
            <xsl:value-of select="current-grouping-key()" />
          </td>
        </tr>
        <tr>
          <td>ID</td><td>Title</td><td>Genre</td><td>Price</td>
        </tr>
        <xsl:for-each select="current-group()">
          <tr>
            <td><xsl:value-of select="@id"/></td>
            <td><xsl:value-of select="title"/></td>
            <td><xsl:value-of select="genre"/></td>
            <td><xsl:value-of select="price"/></td>
          </tr>
        </xsl:for-each>
        <tr>
          <td colspan="3" align="right">Sub Total:</td>
          <td><xsl:value-of select="format-number(sum(current-group()/price), '0.00')" /></td>
        </tr>
      </xsl:for-each-group>
      <tr>
        <td colspan="3" align="right">Sub Total:</td>
        <td><xsl:value-of select="format-number(sum(book/price), '0.00')" /></td>
      </tr>
    </table>
