Xslt xpath:select第n项返回所有

当我使用xpath时，请按照下面的xslt进行选择

我明白了。Fleet1元素包含所有事件

BlueScope负载：178896运行代码：NUNCOL

我甚至试着用a表示每组，并选择…当特定于每次发生时，但仍然得到相同的结果

我不知道如何在choose…when方法中使用此选项

<xsl:number count="EquipmentDetailsLoop[normalize-space(EquipmentDetails/EquipmentStructure/DescriptionCode)='TL']" level="single"></xsl:number>

---

作为一个示例，此样式表：

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:ns="urn:ROCK-BlueScope/ShipmentImportWS"
 exclude-result-prefixes="ns">
    <xsl:strip-space elements="*">
    <xsl:template match="ns:Shipment">
        <ManifestSourceM>
            <xsl:apply-templates/>
        </ManifestSourceM>
    </xsl:template>
    <xsl:template match="ns:ShipmentInformation">
        <DSManifest>
            <xsl:apply-templates/>
        </DSManifest>
    </xsl:template>
    <xsl:template match="ns:ShipmentIdentificationNumber">
        <ManifestNo>
            <xsl:value-of select="."/>
        </ManifestNo>
    </xsl:template>
    <xsl:template match="ns:Date">
        <ManifestDate>
            <xsl:value-of select="."/>
        </ManifestDate>
    </xsl:template>
    <xsl:template match="ns:EquipmentStructure[ns:DescriptionCode='TV']">
        <PrimeMover>
            <xsl:value-of select="ns:EquipmentNumber"/>
        </PrimeMover>
    </xsl:template>
    <xsl:template match="ns:EquipmentStructure[ns:DescriptionCode='TL']">
        <xsl:variable name="vNumber">
            <xsl:number count="ns:EquipmentStructure[ns:DescriptionCode='TL']"
                        level="any"/>
        </xsl:variable>
        <xsl:element name="Fleet{$vNumber}">
            <xsl:value-of select="ns:EquipmentNumber"/>
        </xsl:element>
    </xsl:template>
    <xsl:template match="text()"/>
</xsl:stylesheet>

输出：

<ManifestSourceM>
    <DSManifest>
        <ManifestNo>178896</ManifestNo>
        <ManifestDate>2010-12-09</ManifestDate>

注意：覆盖文本节点内置规则。模式匹配我们只想转换（更高层次）或转换和输出值（LEFS）的任何元素。使用

xsl:element

指令命名数据驱动元素。使用xsl:number指令对层次结构进行编号。

您的问题在于：

ns:EquipmentDetailsLoop
 /ns:EquipmentDetails
  [ns:EquipmentStructure
        /ns:DescriptionCode = 'TL'
  ][1]
      /ns:EquipmentStructure
        /ns:EquipmentNumber[1]

这将从所有

ns:EquipmentDetailsLop

子树中选择所需的

ns:EquipmentNumber

因为您使用的是XSLT 2.0，

指令输出一个文本节点，其中包含节点集中每个节点的字符串值，由

select

属性选择。因此，所有4个字符串都被输出

您想要的：

(/*/*/*/*/*[ns:DescriptionCode='TL']/ns:EquipmentNumber)[$k]

其中，

$k

在范围内（必须用该范围内的每个整数替换一次）：

---

1

到

计数（（/*/*/*/*/*/*[ns:DescriptionCode='TL']/ns:EquipmentNumber））

您确定总有5个“车队”吗？好问题，+1。请参阅我的答案，以获得一个补偿和一个简短而简单的解决方案。：）现在你让我对我的答案有些不确定。这个表达式不是只返回XPath 1.0中的第一个匹配项吗？@biziclop：如果您指的是OP的表达式，它会选择任何已选择节点的每个子节点——XPath 1.0和XPath 2.0都是这样。可能您指的是在XSLT1.0（不是XPath）中，

指令只使用由其

select

属性选择的节点集的第一个节点。是的，这是真的。但是，OP使用的是XSLT 2.0，其中

为节点集中的每个节点输出一个文本节点。谢谢Dimitre的解释。@Tony-J:不客气。此时，公认的感恩方式是接受答案（点击答案旁边的绿色复选标记）。：）再次感谢亚历杭德罗帮我解除头痛。我不得不对Date元素进行一些更改，因为它将拾取所有实例（真正的xml包含更多的数据）。我刚刚将其从模板中删除，并将其作为DSManifest节点中的正常值添加。再次感谢。@Tony J:不客气。关于

ns:Date

模式：使用更具体的模式，如

ns:DateTimeReference/ns:Date

。
