XML 문서를 CSV 플랫 파일로 변환하기위한보다 효율적인 XSLT

Question

XML 문서를 CSV로 변환하고 변환하는 XSLT가 있습니다. 그러나 읽기가 힘들어 ("../../"참조가 모두 마음에 들지 않습니다.) 또한 성능이 손상되는지 궁금합니다. 변환하려는 파일이 큽니다. 몇 가지 다른 예를 살펴 보았지만 그 중 하나만 작동하도록 만들 수있었습니다.

제 질문은 : 입니다. 1.이 XSLT를 "간략하게"및 "../ .."참조를 사용하지 않기 위해 다시 작성할 수 있습니까? 2. "../ .."형식 참조는 값을 저장하는 것보다 덜 효율적입니다.

아래의 샘플. 감사합니다, 존

을 heres XSLT :

<?xml version="1.0"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output method="text"/> 
<xsl:template match="/"> 
    <xsl:apply-templates select="Document"/> 
</xsl:template> 
<xsl:template match="Document"> 
    <xsl:apply-templates select="DocBody"/> 
</xsl:template> 
<xsl:template match="DocBody"> 
    <xsl:apply-templates select="Values"/> 
</xsl:template> 
<xsl:template match="Values"> 
    <xsl:apply-templates select="IntervalValues"/> 
</xsl:template> 
<xsl:template match="IntervalValues"> 
    <xsl:apply-templates select="Quantity"/> 
</xsl:template> 
<xsl:template match="Quantity"> 
    <xsl:value-of select="concat(../../../../DocHeader/DocTitle,',',../../../../DocHeader/CreatedAt,',',../../../DeliveryDate,',',../../../DeliveryHour,',',../Interval,',',Type,',',Value)"/> 
    <xsl:text>&#xA;</xsl:text> 
</xsl:template> 
</xsl:stylesheet>

Heres는 작은 XML 샘플 :

</DocHeader> 
<DocBody>

Answer 1

당신은 조금 일찍 밖으로이 같은 공통 부분을 당겨 수 :

<?xml version="1.0"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output method="text"/> 

<xsl:variable name="head"> 
<xsl:for-each select="Document/DocHeader"> 
    <xsl:value-of select="concat(DocTitle,',',CreatedAt,',')"/> 
</xsl:for-each> 
<xsl:for-each select="Document/DocBody"> 
    <xsl:value-of select="concat(DeliveryDate,',',DeliveryHour,',')"/> 
</xsl:for-each> 
</xsl:variable> 

<xsl:template match="/"> 
<xsl:apply-templates select="Document/DocBody/Values/IntervalValues/Quantity"/> 
</xsl:template> 

<xsl:template match="Quantity"> 
<xsl:value-of select="concat($head,../Interval,',',Type,',',Value)"/> 
<xsl:text>&#xA;</xsl:text> 
</xsl:template> 

</xsl:stylesheet>
