다중 루프가있는 XSLT 변환

Question

아래 XML을 XSLT를 사용하여 변환해야합니다.

입력 XML은 XSLT가 = "페이지 폭"attrQualMany 내부 attrGroupMany = 각 행 "pagetype에"뿐만 아니라, 내부 루프 반복한다

<document> 
<item> 
    <ID>1000909090</ID> 
    <flex> 
     <attrGroupMany name="pageinfo"> 
      <row> 
       <attrQualMany name="pageinput"> 
        <value qual="en">User Intake</value> 
       </attrQualMany> 
       <attrGroupMany name="pagetype"> 
        <row> 
         <attr name="pagemeasure">EXACT</attr> 
         <attrQualMany name="pagecontain"> 
          <value qual="GR">12</value> 
         </attrQualMany> 
        </row> 
        <row> 
         <attr name="pagemeasure">EXACT</attr> 
         <attrQualMany name="pagecontain"> 
          <value qual="JH">13</value> 
         </attrQualMany> 
        </row> 
       </attrGroupMany> 
       <attr name="pagestate">PREPARED</attr> 
       <attrQualMany name="pagewidth"> 
        <value qual="OZ">10</value> 
        <value qual="AB">11</value> 
       </attrQualMany> 
      </row> 
     </attrGroupMany> 
    </flex> 
</item> 
</document> 

이다. 그래서 그것은 4 * 2 * 2 회 루프가됩니다.

출력은

<xsl:value-of select="concat('PAGEDETAILSINFO','-',ancestor::item/id,../../attr[@name='pagestate'], '-', pagewidthValue ,'-', pagewidthuom, '-', attr[@name='pagemeasure'] , '-',pagecontainValue, '-', pagecontainUOM )"/> 

의 CONCAT해야하며, 예상 출력은

<?xml version="1.0" encoding="UTF-8"?> 
<CatalogItem> 
<RelationshipData> 
    <Relationship> 
     <RelationType>PAGEDETAILSINFO</RelationType> 
     <RelatedItems count="4"> 
      <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-12-GR" /> 
      <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-13-JH" /> 
      <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-12-GR" /> 
      <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-13-JH" />     
     </RelatedItems> 
    </Relationship> 
</RelationshipData> 
</CatalogItem> 

나는 내부와 내 XSLT 모두 외부 루프 수없는 생각이다. XSLT 아래에서 사용하고 있습니다.

이 문제는 몇 가지 변수를 사용하면 쉽게 해결할 수 있습니다.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> 
    <xsl:output indent="yes" /> 
    <xsl:template match="document/item"> 
    <xsl:variable name="item" select="." /> 
    <xsl:variable name="pageinfo" select="flex//attrGroupMany[@name = 'pageinfo']/row" /> 
    <xsl:variable name="pagetype" select="flex//attrGroupMany[@name = 'pagetype']/row" /> 
    <xsl:variable name="pagewidth" select="flex//attrQualMany[@name = 'pagewidth']/value" /> 
    <CatalogItem> 
     <RelationshipData> 
     <Relationship> 
      <RelationType>PAGEDETAILSINFO</RelationType> 
      <RelatedItems count="{count($pagetype) * count($pagewidth)}"> 
      <xsl:for-each select="$pagetype"> 
       <xsl:variable name="t" select="." /> 
       <xsl:for-each select="$pagewidth"> 
       <xsl:variable name="w" select="." /> 
       <RelatedItem referenceKey="PAGEDETAILSINFO-{$item/ID}-{$pageinfo/attr[@name='pagestate']}-{$w}-{$w/@qual}-{$t/attr[@name='pagemeasure']}-{$t//value}-{$t//value/@qual}" /> 
       </xsl:for-each> 
      </xsl:for-each> 
      </RelatedItems> 
     </Relationship> 
     </RelationshipData> 
    </CatalogItem> 
    </xsl:template> 
</xsl:stylesheet>
