早上好，
我的代码中有相同的节点，它们都有其他百分比。我只想要百分比最高的节点。我似乎无法让我的代码正确。有没有办法在这个上使用 max 函数？
<xsl:template match="/">
<xsl:for-each select="/x:Invoice/cac:InvoiceLine/cac:TaxTotal/cac:TaxSubtotal/cac:TaxCategory">
<xsl:choose>
<xsl:when test="count(cbc:Percent) = 1">
<xsl:value-of select="format-number(cbc:Percent,'00')"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="21"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
我试过上面的代码。现在我得到结果 0021212121。所以代码选择了 cbc:Percent 中的所有字段。

在这段代码中，最高百分比是 21，所以我只想要 21 作为结果而不是节点中的所有结果..有人可以帮我写代码吗？？
我认为你可以在没有扩展功能的情况下做到这一点。您当前的代码似乎表明您可以拥有多个Percent（或者根本没有）。如果是这样，试试这个模板
<xsl:template match="/">
<xsl:for-each select="/x:Invoice/cac:InvoiceLine/cac:TaxTotal/cac:TaxSubtotal/cac:TaxCategory">
<xsl:sort select="cbc:Percent * (count(cbc:Percent) = 1) + 21 * (1 - (count(cbc:Percent) = 1))" order="descending" />
<xsl:if test="position() = 1">
<xsl:choose>
<xsl:when test="count(cbc:Percent) = 1">
<xsl:value-of select="format-number(cbc:Percent,'00')"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="21"/>
</xsl:otherwise>
</xsl:choose>
</xsl:if>
</xsl:for-each>
</xsl:template>
如果你只能有零或百分之一，你可以把它简化成这样......
<xsl:sort select="cbc:Percent * count(cbc:Percent) + 21 * count(cbc:Percent)" order="descending" />
而且，当然，如果所有节点总是有一个，Percent你可以这样做......
<xsl:sort select="cbc:Percent" />
