在上面你可以找到我得到的一段XML。我想要以下内容：如果 ItemClassificationCode 是 83101800 并且 Item/Description 是 "Termijnbedrag Elektriciteit" 那么 "Elektra1" Elseif ItemClassificationCode 是 83101800 并且 Item/Description 是 "Netbeheerkosten" 那么 "Net1" Elseif ItemClassificationCode 是83101800那么 "Elektra" Else ">

我尝试了以下方法：

<xsl:template match="/">
<xsl:for-each select="/*[local-name()='InvoiceLine']">
<xsl:if test="*[local-name()='Item']/*[local-name()='CommodityClassification']/*[local-name()='ItemClassificationcode']='83101800'">Elektra</xsl:if>
<xsl:if test="*[local-name()='Item']/*[local-name()='CommodityClassification']/*[local-name()='ItemClassificationcode']='83101800' and *[local-name()='Item']/*[local-name()='Description']='Netbeheerkosten'">Net1</xsl:if>
<xsl:if test="*[local-name()='Item']/*[local-name()='CommodityClassification']/*[local-name()='ItemClassificationcode']='83101800' and *[local-name()='Item']/*[local-name()='Description']='Termijnbedrag Elektriciteit'">Elektra1</xsl:if>
</xsl:for-each>
</xsl:template>

但是，上面的代码只是从所有内容中获取结果。所以 ElektraNet1Elektra1，但我只想要 Net1 或 Elektra 1，如果 InvoiceLine 有两个变量都依赖于它。因此，如果项代码83101800并且描述显示Netbeheerkosten，那么它应该只是Net1和Net1。

有人可以帮我吗？我也尝试过xsl：otherwhise 当等。但我似乎没有让它工作。

Answer 1

这就是模板规则的用途：

<xsl:template match="/ubl:Invoice">
<xsl:apply-templates select="cac:InvoiceLine[cac:Item/cac:CommodityClassification/cbc:ItemClassificationcode='83101800']">
</xsl:template>
<xsl:template match="cac:Item[cbc:Description='Netbeheerkosten']">Net1</xsl:template>
<xsl:template match="cac:Item[cbc:Description='Termijnbedrag Elektriciteit']">Net1</xsl:template>
<xsl:template match="cac:Item">Elektra</xsl:template>

Answer 2

试试这个方式：

<xsl:template match="/ubl:Invoice">
<xsl:for-each select="cac:InvoiceLine[cac:Item/cac:CommodityClassification/cbc:ItemClassificationcode='83101800']">
<xsl:choose>
<xsl:when test="cac:Item/cbc:Description='Netbeheerkosten'">Net1</xsl:when>
<xsl:when test="cac:Item/cbc:Description='Termijnbedrag Elektriciteit'">Elektra1</xsl:when>
<xsl:otherwise>Elektra</xsl:otherwise>
</xsl:choose>
<xsl:text>&#10;</xsl:text>
</xsl:for-each>
</xsl:template>

这要求样式表包含源 XML 中使用的命名空间声明。
