Question

我正在尝试根据日期比较添加新元素。如果父DATE在过去7天内，我想添加一个新元素。我编写了代码来进行日期比较，但是我很难搞清楚它的位置。目前，它在模板中重新格式化父DATE，但这会导致我的新元素在日期元素中。有没有办法在当前元素之外创建一个新元素？感谢。

Answer 1

如果匹配DATE元素而不是文本节点，则可以执行此操作：

    <xsl:template match="DATE">
        <xsl:variable name="dStr" select="string(.)" />
        <xsl:variable name="bdStr" select="string($backdate1)" />
        <!-- format DATE mm/dd/yyyy -->
        <xsl:copy>
          <xsl:value-of select="concat(substring($dStr, 1, 2), '/', 
                                       substring($dStr, 3, 2), '/', 
                                       substring($dStr, 5, 4))"/>
        </xsl:copy>
        <!-- add new node mostrecent if date is within the last 7 days -->
        <xsl:variable name="subtract_date" 
                      select="days-from-duration(xs:date(
                                          concat(substring($dStr, 5, 4), '-', 
                                                 substring($dStr, 1, 2), '-', 
                                                 substring($dStr, 3, 2))) - 
                              xs:date(substring($bdStr, 1, 10)))"/>
        <xsl:if test="$subtract_date &gt;= 0">
          <mostrecent>YES</mostrecent>
        </xsl:if>
    </xsl:template>
