XSLT遞歸

我有下面的xml，我需要，我們需要利用我們已經來達到的XSLT遞歸

輸入XML我已經引用爲具有子節點如下最頂層節點XSLT轉換爲預期輸出XML：

問題我現在面臨的是如預期的標籤<isFlowServiceDisabled>所寫的條件無法正常工作。含義我得到的標籤爲空值，不知道我的XSLT有什麼問題。除了XSLT中的其他條件外，我還希望強制執行一個規則，如果節點<isFlowServiceDisabled>的值爲「false」，那麼只包含或不包含。

請告訴我什麼是空值。

我覺得下面應該是固定的，

你不需要下面的模板。你也不應該使用xsl：在這裏選擇只會做。此外，您還添加了xsl：copy-of select =「isFlowServiceDisabled」，它將覆蓋您的模板調用。我已經刪除它。

<xsl:template match="isFlowServiceDisabled" > 

    <xsl:choose> 
     <xsl:when test="isFlowServiceDisabled[contains(., 'false')]"> 
      <isFlowServiceDisabled> 
       <xsl:value-of select="isFlowServiceDisabled" /> 
      </isFlowServiceDisabled> 
     </xsl:when> 
     <xsl:otherwise/> 

    </xsl:choose> 

</xsl:template>

應該不用模板來完成，

<xsl:if test="isFlowServiceDisabled = 'false'"> 
    <isFlowServiceDisabled> 
      false 
    </isFlowServiceDisabled> 
</xsl:if>

謝謝您的輸入。那麼再次我有一個問題：當是已經在那裏，因爲我想整個我值「真」，那麼在我的XML輸出它與空值來跳過如果是真實的。如何爲此調整xslt？ – Nis

@Nis請接受我對你原來問題的回答。然而，對於新的要求，你可以檢查isServiceDisabled類似isFlowServiceDisabled，把參考塊進去 – ScanQR

@Nis沒有這個解決您的查詢？ – ScanQR
