这是我的XSL文件。

<?xml version="1.0"?>
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">

<html> <head><title>Customers</title></head> <body> <table rules="all">
<thead><tr><th>Customer</th><th>Number of Cars Purchased</th></tr></thead> 
  <xsl:for-each select="cars/car">
  <tr><td>  <xsl:apply-templates select="customerID"/> </td>
  </xsl:for-each>
</table></body></html>

</xsl:template>
</xsl:transform>

提前致谢。

有很多方法可以做这些事情，但不确定你在那里做什么。如果你想根据顾客做一张桌子，你就无法从汽车中开始。您需要每行一个客户，因此您必须通过计算它们的客户进行迭代。

像这样的东西

<?xml version="1.0"?>
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html"/>
    <xsl:template match="/">

        <html> <head>
            <title>Customers</title></head> <body> 
                <table rules="all">
                    <thead>
                        <tr><th>Customer</th><th>Number of Cars Purchased</th>                            </tr>
                    </thead> 
                    <xsl:for-each select=".//customerID">
                        <xsl:variable name="customerId" select="text()"/>
                        <xsl:if test="not(preceding::customerID) or $customerId != preceding::customerID[1]">
                       <tr>
                           <td>  <xsl:value-of select="."/></td>
                           <td><xsl:value-of select="count(following::customerID[text()=$customerId])+1"/></td>
                       </tr>
                        </xsl:if>
                   </xsl:for-each>
                </table>
            </body>
        </html>
    </xsl:template>
</xsl:transform>

虽然这有点乱，可以很多精炼（我必须用完！）
