基於其他元素的值移除XML元素

Question

我必須在下面實現。

if if <m_control>/<initiator_id> is Dummy then xml element <note>/<reason> should be removed.Below is the hirarchy of note element。

<o:m_content/o:application/o:product/o:client_specific_illustration/o:note> 

下面是示例XML：

<?xml version="1.0"?> 
<message xmlns="http://www.origoservices.com" xmlns:ns2="http://www.w3.org/2000/09/xmldsig#"> 

<m_control>

以下是我已經嘗試了XSLT，但我沒有得到預期的輸出，當音符/元素的原因是沒有得到清除。

<?xml version="1.0"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:o="http://www.origoservices.com" xmlns:dp="http://www.datapower.com/extensions" xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:date="http://exslt.org/dates-and-times" version="1.0" extension-element-prefixes="dp" exclude-result-prefixes="fn date"> 
    <xsl:output omit-xml-declaration="yes" indent="yes"/> 
    <xsl:strip-space elements="*"/> 
    <xsl:output method="xml" indent="yes"/> 
    <xsl:template match="node()|@*"> 
    <xsl:copy> 
     <xsl:apply-templates select="node()|@*"/> 
    </xsl:copy> 
    </xsl:template> 

    <xsl:template match="o:m_content/o:application/o:product/o:client_specific_illustration/o:note[../../../../../o:m_control/o:initiator_id='TEX']"> 

    </xsl:template> 
</xsl:stylesheet> 

有沒有人請讓我知道，我在哪裏comiting錯誤？

問候。

Answer 1

只需要一個變量來存儲initiator_id。如下圖所示：

<xsl:variable name="test" select="o:message/o:m_control/o:initiator_id"/> 

然後，測試note節點

<xsl:template match="o:note[parent::o:client_specific_illustration]"> 
    <xsl:choose> 
     <xsl:when test="$test='Dummy'"></xsl:when> 
     <xsl:otherwise> 
      <xsl:copy> 
       <xsl:apply-templates/> 
      </xsl:copy> 
     </xsl:otherwise> 
    </xsl:choose> 
</xsl:template> 

因此，完整的樣式表是：

<?xml version="1.0"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:o="http://www.origoservices.com" xmlns:dp="http://www.datapower.com/extensions" 
    xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:date="http://exslt.org/dates-and-times" 
    version="1.0" extension-element-prefixes="dp" exclude-result-prefixes="fn date"> 

    <xsl:output omit-xml-declaration="yes" indent="yes"/> 

    <xsl:strip-space elements="*"/> 

    <xsl:output method="xml" indent="yes"/> 

    <xsl:variable name="test" select="o:message/o:m_control/o:initiator_id"/> 

    <xsl:template match="node()|@*"> 
     <xsl:copy> 
      <xsl:apply-templates select="node()|@*"/> 
     </xsl:copy> 
    </xsl:template> 

    <xsl:template match="o:note[parent::o:client_specific_illustration]"> 
     <xsl:choose> 
      <xsl:when test="$test='Dummy'"></xsl:when> 
      <xsl:otherwise> 
       <xsl:copy> 
        <xsl:apply-templates/> 
       </xsl:copy> 
      </xsl:otherwise> 
     </xsl:choose> 
    </xsl:template> 
</xsl:stylesheet> 

作爲替代，你可以使用

<xsl:template match="o:m_content[preceding-sibling::o:m_control/o:initiator_id='Dummy']/o:application/o:product/o:client_specific_illustration/o:note"/>
