XSLT 1.0 计数和删除

Question

我需要检查一个“Item”是否有多个名为“ItemDeliveryInformation”的节点，如果有，节点“PackingSlipId”的值是否为“ohne Lieferschein”。例如一个带有“PackingSLipId = ohne Lieferschein”的节点“ItemDeliveryInformation”是可以的，但是如果“Item”处有两个或更多节点“ItemDeliveryInformation”也可以，但是如果这几个节点之一的值为“ohne Lieferschein”在“PackingSlipId”处，XSLT 必须删除整个节点“ItemDeliveryInformation”，其中“PackingSlipId = ohne Lieferschein”。

我是这样开始的：

<xsl:template match="Item[count(./ItemDeliveryInformation &lt; 1)] and Item/ItemDeliveryInformation[./PackingSlipId = 'ohne Lieferschein']">   
        <xsl:choose>
            <xsl:when test="Item[count(./ItemDeliveryInformation &lt; 1)] and Item/ItemDeliveryInformation[./PackingSlipId = 'ohne Lieferschein']"></xsl:when>
                <xsl:otherwise> <xsl:apply-templates select="@* | node()"/></xsl:otherwise>
        </xsl:choose>
    </xsl:template>

Answer 1

Item[…] and Item/ItemDeliveryInformation[…] 永远不会匹配，因为没有节点既是 Item 又是 ItemDeliveryInformation。不要在匹配中复制条件，那没有意义。

您想在 ItemDeliveryInformation 上进行匹配，如果它同时具有 ohne Lieferschein 和兄弟节点，则将其删除。由于remove是没有复制，所以复制的时候把条件倒过来：

<xsl:template match="Item/ItemDeliveryInformation">
  <xsl:if test="count(preceding-sibling::ItemDeliveryInformation|following-sibling::ItemDeliveryInformation)=0 or PackingSlipId/text() != 'ohne Lieferschein'">
    <xsl:copy><xsl:apply-templates select="@* | node()"/></xsl:copy>
  </xsl:if>
</xsl:template>

这假设您有一个通用的复制模板。
