推荐答案
这种转变:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/*">
<html>
<table border="1">
<thead>
<tr>
<td>Name</td><td>Total</td>
</tr>
</thead>
<xsl:apply-templates/>
</table>
</html>
</xsl:template>
<xsl:template match="customer">
<tr>
<td><xsl:value-of select="clientname"/></td>
<td><xsl:value-of select=
"sum(invoices/product/(PriceUnit*Ordered))"/></td>
</tr>
</xsl:template>
</xsl:stylesheet>
应用于以下 XML 文档时(在纠正严重格式错误的提供文本后获得):
when applied on the following XML document (obtained after correcting the severely malformed provided text):
<customers>
<customer>
<clientname>troy madison</clientname>
<invoices>
<invoiceDate>8/8/98</invoiceDate>
<product>
<PriceUnit>1000</PriceUnit>
<Ordered>2</Ordered>
</product>
<product>
<PriceUnit>5400</PriceUnit>
<Ordered>3</Ordered>
</product>
</invoices>
<invoices>
<invoiceDate>1/4/98</invoiceDate>
<product>
<PriceUnit>300</PriceUnit>
<Ordered>4</Ordered>
</product>
<product>
<PriceUnit>6000</PriceUnit>
<Ordered>1</Ordered>
</product>
</invoices>
<invoices>
<invoiceDate>03/5/99</invoiceDate>
<product>
<PriceUnit>549</PriceUnit>
<Ordered>1</Ordered>
</product>
<product>
<PriceUnit>320</PriceUnit>
<Ordered>2</Ordered>
</product>
</invoices>
</customer>
<customer>
<clientname>Morris</clientname>
<invoices>
<invoiceDate>1/1/00</invoiceDate>
<product>
<PriceUnit>59</PriceUnit>
<Ordered>3</Ordered>
</product>
<product>
<PriceUnit>55</PriceUnit>
<Ordered>1</Ordered>
</product>
</invoices>
<invoices>
<invoiceDate>11/1/01</invoiceDate>
<product>
<PriceUnit>10</PriceUnit>
<Ordered>2</Ordered>
</product>
<product>
<PriceUnit>54</PriceUnit>
<Ordered>1</Ordered>
</product>
</invoices>
<invoices>
<invoiceDate>03/2/01</invoiceDate>
<product>
<PriceUnit>30</PriceUnit>
<Ordered>1</Ordered>
</product>
<product>
<PriceUnit>299</PriceUnit>
<Ordered>1</Ordered>
</product>
</invoices>
</customer>
</customers>
产生(只能猜测是什么！！！)想要的结果:
<html>
<table border="1">
<thead>
<tr>
<td>Name</td>
<td>Total</td>
</tr>
</thead>
<tr>
<td>troy madison</td>
<td>26589</td>
</tr>
<tr>
<td>Morris</td>
<td>635</td>
</tr>
</table>
</html>
