如何在XSLT1.0/xml中使用else函数 4. 10825 405.94 2020-01-01 2020-01-08 奥普拉斯-杜尔扎姆能源公司（schijf 2） 奥普拉斯-杜尔扎姆能源公司（schijf 2） 83101800 s 21 增值税 0.0375000 5. -0.02185792 -9.52 2020-01-01 2020-01-08 内贝赫尔科斯滕酒店 内贝赫尔科斯滕酒店 83101800 s 21 增值税 435.6800000 1. 0.25810000 0 2020-01-01 2020-02-08 Termijnbedrag Elektriciteit Termijnbedrag Elektriciteit 83101800 s 21 增值税 0

在上面，您可以找到我得到的一段XML。我想要以下信息：如果ItemClassificationCode是83101800，Item/Description是“Termijnbedag Elektriciteit”，那么“Elektra1”Elseif ItemClassificationCode是83101800，Item/Description是“Netbeheerkosten”，那么“Net1”Elseif ItemClassificationCode是83101800，那么“Elektra”Else

我尝试了以下方法：

然而，上面的代码只是让我得到了一切的结果。所以ElektraNet1Elektra1，但我只想要Net1或elektra1，如果InvoiceLine有两个依赖于它的变量。因此，如果itemcode为83101800，且描述为Netbeheerkosten，则应为Net1，且仅为Net1

有人能帮我吗？我还尝试了xsl:otherwhise-when-when等。。但我似乎无法让它发挥作用。

试着这样做：

<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>

这要求样式表包含源XML中使用的命名空间声明

这就是模板规则的作用：

<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>

使用。--请注意，使用前缀而不是

*[local-name（）='…']

hack。您能帮我解决这个问题吗？我对xsl非常陌生（+/-1年）。不，因为您的XML不完整，并且没有显示预期的结果。请参阅：。预期结果应该是（在这种情况下）：Elektra（第1行）Net1（第2行）和Elektra 1（第3行）谢谢！！这是为了我。

<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>
