我是xslt的新手。我正在创建一个转换，需要根据税率计算税额。输入文件包含不同的税率和税额。要求是寻找通用税率，取单个税额并将其全部加起来。这将创建一个T元素。
如果存在多个税率，请对普通税额进行分组并将其总计，并形成T元素。
例如：输入文件为：

我的输出应与此类似：
<H>
<tax rate 20>
<tax amount 102.60>
</H>
<H>
<tax rate 7>
<tax amount 21.50>
</H>
<H>
<tax rate 19>
<tax amount 13.28>
</H>
我的xslt是：
<xsl:variable name="vTaxRateCount" select="count(distinct-values(LIST_G_LINES/G_LINES/TAXRATE))"/>
<xsl:variable name="vDistinct">
<xsl:for-each select="fn:distinct-values(LIST_G_LINES/G_LINES/TAXRATE)">
<xsl:element name="Values">
<xsl:value-of select="."/>
</xsl:element>
</xsl:for-each>
</xsl:variable>
<xsl:variable name="vPath" select="LIST_G_LINES/G_LINES/TAXAMOUNT"/>
<xsl:for-each select="$vDistinct/Values">
<xsl:variable name="vUniqueVal" select="."/>
<xsl:for-each select="LIST_G_LINES/G_LINES/TAXRATE=.">
<xsl:element name="TaxAmount">
<xsl:value-of select="sum($vPath[@TAXRATE = $vUniqueVal])"/>
<xsl:value-of select="$vUniqueVal"/>
</xsl:element>
</xsl:for-each>
</xsl:for-each>
此代码似乎无效。你能帮忙吗？
答案 0 :(得分：2)
根据您输入的内容和给定的XSLT，假设输入文件如下：（如果它是 XML ）
<?xml version="1.0" encoding="UTF-8"?>
<LIST_G_LINES>
<G_LINES>
<Taxrates> 20 <Taxamount> 1.60 </Taxamount></Taxrates>
</G_LINES>
<G_LINES>
<Taxrates> 7 <Taxamount> 21.50 </Taxamount></Taxrates>
</G_LINES>
<G_LINES>
<Taxrates> 19 <Taxamount> 1.60 </Taxamount></Taxrates>
</G_LINES>
<G_LINES>
<Taxrates> 19 <Taxamount> 11.68 </Taxamount></Taxrates>
</G_LINES>
<G_LINES>
<Taxrates> 20 <Taxamount> 101 </Taxamount></Taxrates>
</G_LINES>
</LIST_G_LINES>
XSLT 2.0解决方案可以如下：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/LIST_G_LINES">
<xsl:for-each-group select="G_LINES" group-by="Taxrates/text()">
<H>
<TaxRate>
<xsl:value-of select="current-grouping-key()" />
</TaxRate>
<TaxAmount>
<xsl:value-of select="sum(current-group()/Taxrates/Taxamount)" />
</TaxAmount>
</H>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
请参考here以查看输出
编辑：根据更新的 XML ，您可以尝试以下 XSLT 3.0 解决方案：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:math="http://www.w3.org/2005/xpath-functions/math"
exclude-result-prefixes="xs math" version="3.0">
<xsl:mode streamable="yes" />
<xsl:output method="xml" indent="yes" />
<xsl:template match="/">
<xsl:for-each-group select="DATA/LIST_G_TRX/G_TRX/LIST_G_HEADER/G_HEADER/LIST_G_LINES/G_LINES" composite="yes" group-by="TAXRATE">
<xsl:if test="current-grouping-key() != ''">
<H>
<TaxRate>
<xsl:value-of select="current-grouping-key()" />
</TaxRate>
<TaxAmount>
<xsl:value-of select="sum(current-group()/TAXAMOUNT)" />
</TaxAmount>
</H>
</xsl:if>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
