自定义日期的 XSLT-2.0 转换

Question

当给定日期是当月的第一天时，如何在 xslt 中编写自定义日期函数，那么该日期应该是当月的第一天，否则除当月第一天以外的任何日期，然后是下个月的第一天.在给定的示例中，日期为 2019 年 3 月 4 日，当前月份为 2019 年 3 月，如果日期为 2019 年 3 月 1 日，则输出应为 return 2019 年 4 月 1 日，则输出应为 return 2019 年 3 月 1 日。

Answer 1

你可以使用这个功能

<xsl:function name="ad:dateNextMonth">
  <xsl:param name="curDateString"/>
  <xsl:variable name="curDate" select="xs:date(concat(substring($curDateString,1,4),'-',substring($curDateString,5,2),'-',substring($curDateString,7,2)))"/>
  <xsl:variable name="newDate" select="if (day-from-date($curDate) = 1) then format-date($curDate,'[MNn] [D1o] [Y]') else format-date($curDate + xs:yearMonthDuration('P1M'),'[MNn] 1st [Y]')" />
  <xsl:value-of select="concat(substring(substring-before($newDate,' '),1,3),' ',substring-after($newDate,' '))" />
</xsl:function>

像

一样应用它

<xsl:value-of select="ad:dateNextMonth(ancestor::ad:Sale_Tx_Entry/ad:saleDate)" />

它应该按预期工作。你的例子的结果应该是 Apr 1st 2019.

Answer 2

下一个月的第一天的日期可以从给定日期计算为：

$date - (day-from-date($date) - 1) * xs:dayTimeDuration('P1D') + xs:yearMonthDuration('P1M')

如果您只想将其设置为非当月第一天的日期，请将变量定义为：

<xsl:variable name="day" select="day-from-date($date)"/>

并将其作为条件：

if ($day = 1) then $date else $date - ($day - 1) * xs:dayTimeDuration('P1D') + xs:yearMonthDuration('P1M')

将输入强制转换为有效日期并格式化输出留作 reader.
