上面你可以找到我得到的 XML 的一部分。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" 然后 "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>

然而，上面的代码只是让我得到了所有的结果。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，如果商品代码是 83101800 并且描述中写着 Netbeheerkosten，那么它应该是 Net1 并且只有 Net1..

有人可以帮助我吗？我也尝试过 xsl:otherwhise when etc..但我似乎没有让它工作。

Answer 1

这样试试：

<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>

这要求您的样式表包含源 XML 中使用的命名空间声明。

Answer 2

这是模板规则的用途：

<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>
