我想添加一個基於日期比較新的元素。如果父DATE在最近7天內,我想添加一個新元素。我編寫了代碼來進行日期比較,但我很難弄清楚在哪裏放置它。目前,它在模板中重新格式化父DATE,但這會導致我的新元素在日期元素內。有沒有辦法在當前元素之外創建一個新元素?謝謝。XSLT添加新節點之外當前節點的

你可以做到這一點,如果你的日期元素,而不是它的文本節點上一致:

<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>

感謝JL,偉大的工作。問題:使用導致我的原始代碼無法工作的文本節點的是什麼? –

它並沒有因爲你的方法工作,身份模板是做'DATE'元素複製到輸出,然後應用_inside_該元素模板'DATE'的兒童(包括文字)的工作。因此,在'text()'模板中可以使用的任何內容都將被輸出_inside_ DATE'元素。一旦你在那裏,沒有辦法讓它回到外面。 – JLRishe

我試圖將上述xslt從1.0轉換爲2.0。當我這樣做時,我收到一個錯誤:substring()的第一個參數的必需項目類型是xs:string;提供的值具有項目類型xs:date。我不明白的是,爲什麼這個轉換工作在1.0而不是2.0以及如何解決它。我在想,2.0需要更多的變量聲明控制。此外,錯誤似乎來自我的if語句,因爲當我註釋掉它時,代碼編譯得很好。 –
