XSLT를 사용하여 XML을 변환하는 데 도움이 필요합니다.

Question

ID/복사 패턴을 사용하여 아래의 세그먼트/세그먼트 부분 만 변환하고 나머지 구조는 유지하려고합니다. 템플릿은 어떻게 생겼을까요? 나는 xslt : for-each SegmentFares/Segments/Segment에 템플릿을 적용하기 위해 포럼에서 몇 가지 예제를 시도했지만 첫 번째 SegmentFare에 기본 요금을 넣는 방법을 알지 못하고 나머지 SegmentFare의 후속 항목을 0으로 설정하는 방법을 모르겠습니다. 세그먼트.

Answer 2

<xsl:for-each>에 대한 당신의 생각 좋았다; 아래와 같이 할 수 있습니다.

중요한 부분은 <xsl:choose> 요소입니다. 현재 컨텍스트 노드는 <Segment> 요소 (<xsl:for-each> 루프 반복)입니다. 따라서 조건 <xsl:when>은 으로 계산됩니다. 현재 요소 앞에있는 경우 동일한 부모 요소에 다른 <Segment> 요소가 없습니다. 이것이 이면 원래의 <BaseFare> 값이 복사되고, 그렇지 않으면 <BaseFare>이 0으로 삽입됩니다.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output omit-xml-declaration="yes" indent="yes"/> 

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

    <xsl:template match="/FareQuoteRS/PaxFareQuotes/item/SegmentFares"> 
     <xsl:copy> 
      <xsl:for-each select="SegmentFare/Segments/Segment"> 
       <SegmentFare> 
        <xsl:copy-of select="../../Currency"/> 
        <xsl:choose> 
         <xsl:when test="not(preceding-sibling::Segment)"> 
          <xsl:copy-of select="../../BaseFare"/> 
         </xsl:when> 
         <xsl:otherwise> 
          <BaseFare>0</BaseFare> 
         </xsl:otherwise> 
        </xsl:choose> 
        <Segments> 
         <xsl:copy> 
          <xsl:apply-templates select="node()|@*"/> 
         </xsl:copy> 
        </Segments> 
       </SegmentFare> 
      </xsl:for-each> 
     </xsl:copy> 
    </xsl:template>
