上面您可以找到我得到的XML片段。我想要以下内容：如果ItemClassificationCode为83101800且Item / Description为“ Termijnbedrag Elektriciteit”，则“ Elektra1” Elseif ItemClassificationCode为83101800且Item / Description为“ Netbeheerkosten”然后“ Net1” Elseif ItemClassificationCode为83101800则为“ Elektra” Else“”] >

我尝试了以下操作：

<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让我从一切中得到结果。所以是ElektraNet1Elektra1，但是如果InvoiceLine具有两个依赖于它的变量，我只想使用Net1或Elektra 1。因此，如果项目代码为83101800并且描述为Netbeheerkosten，则它应仅为Net1和Net1。]

有人可以帮我吗？我也曾用xsl：otherwhise尝试过，等等。但是我似乎无法正常工作。
