Question

我有一个项目，我需要在XML文档中获取和计算标记中的不同值。如果你看一下XML，我特意试着计算星期二不同的WorkOrderNumbers数。稍后我会做周一等等。我试过以下代码。

    <xsl:variable name="tmp" select="count(//Tuesday/TimeDetail/WorkOrderNumber[generate-id() = generate-id(key('distinctWorkOrder', .)[1])])"></xsl:variable>

返回2.我也尝试了这个

    <xsl:variable name="tmp2" select="count(//Tuesday/TimeDetail/WorkOrderNumber[not(.=/preceding-sibling::WorkOrderNumber)])"></xsl:variable>

它返回4.正确的答案是3。

我在下面添加了XML。有人可以指出我做错了什么吗？非常感谢。

Answer 1

此XSLT 2.0 xpath表达式将计算不同的工作订单...

count(fn:distinct-values(/*/*/Tuesday/*/WorkOrderNumber))

这是XSLT 1.0的等价物......

count(/*/*/Tuesday/*/WorkOrderNumber[not(. = following::WorkOrderNumber)])

Answer 2

如果您要查找给定日期的不同元素，则需要确保日元素的名称构成键的一部分

<xsl:key name="distinctWorkOrder" 
   match="TimeDetail" 
   use="concat(local-name(..), '|', WorkOrderNumber)" />

因此，这将使用日期和工单号。然后你可以像这样计算给定日期的不同项目

<xsl:variable name="tmp" 
 select="count(//Tuesday/TimeDetail
  [generate-id() 
  = generate-id(key('distinctWorkOrder', concat(local-name(..), '|', WorkOrderNumber))[1])])"/>

这应该给出答案3.
