爲空元素添加xsi：nil =「true」

Question

我試圖找出一種爲空元素添加xsi：nil =「true」的方法。我可以在輸出上寫一個單獨的xsl來實現這一點，但是試圖弄清楚我是否可以將它寫入當前的xsl本身。

電流XSL從上面的xsl

Answer 1

編輯： 由於您的輸入XML已經有XSI：對空元素nil屬性，所有你需要做的就是添加<xsl:copy-of select="@xsi:nil"/>到你生成的元素的部件。

---

你可以檢查每一個元素，如果其結果將是空的：

<xsl:element name="Name"> 
    <xsl:if test="*:Name=''"> 
     <xsl:attribute name="xsi:nil>true</xsl:attribute> 
    </xsl:if> 
    <xsl:value-of select="*:Name"/> 
</xsl:element> 

或做這一切一氣呵成在可變寫賬目給一個變量，比循環和檢查空：

<xsl:template match="*:objects"> 
<xsl:element name="objects" xmlns="urn:sobject.partner.soap.sforce.com"> 
    <!-- write accounts to variable --> 
    <xsl:variable name="Accounts"> 
     <xsl:for-each select="*:Account"> 
      <xsl:element name="Account"> 

      <xsl:variable name="fsparentid" select="*:ParentId"/> 
      <xsl:variable name="fsconsultingfirmid" select="*:Consulting_Firm__c"/> 

      <xsl:element name="Name"> 
       <xsl:value-of select="*:Name"/> 
      </xsl:element> 

      ... 

     </xsl:element> 

    </xsl:for-each> 
    </xsl:variable> 

    <xsl:for-each select="$Account"> 
    <xsl:copy> 
     <xsl:for-each select="*"> 
      <xsl:choose> 
       <xsl:when test=".=''"> 
       <xsl:copy> 
        <xsl:attribute name="xsi:nil">true</xsl:.attribute> 
       </xsl:copy> 
       <xsl:otherwise> 
        <xsl:copy-of select="."/> 
       </xsl:otherwise> 
       </xsl:when> 
      </xsl:choose> 
     </xsl:for-each> 
    </xsl:copy> 
    </xsl:for-each> 
</xsl:element> 
</xsl:template>
