XSLT Удаление дубликатов с несколькими циклами

Question

Мне нужно преобразовать приведенный ниже XML с помощью XSLT.

Входной XML-это

<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="GR1">20</value> 
          <value qual="GR2">21</value> 
         </attrQualMany> 
        </row> 
        <row> 
         <attr name="pagemeasure">EXACT</attr> 
         <attrQualMany name="pagecontain"> 
          <value qual="JH1">30</value> 
          <value qual="JH2">31</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> 

XSLT должен быть петельные внутри attrGroupMany = "типа страницы" для каждой строки, а также петли внутри attrQualMany = "pagecontain", а затем цикл внутри attrQualMany = " pagewidth ". поэтому он становится 2 * 2 * 2 раза петлями, что в 8 раз.

Выход должен быть Concat из

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

ожидаемого выхода должен быть

<?xml version="1.0" encoding="UTF-8"?> 
<CatalogItem> 
<RelationshipData> 
    <Relationship> 
    <RelationType>PAGEDETAILSINFO</RelationType> 
    <RelatedItems count="8"> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-20-GR1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-20-GR1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-21-GR2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-21-GR2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-30-JH1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-30-JH1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-31-JH2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-31-JH2" /> 
    </RelatedItems> 
    </Relationship> 
</RelationshipData> 
</CatalogItem> 

Но я получаю повторяющиеся строки в выводе, а также счетчик становится в два раза.

Фактический выход ниже неправильного.

<?xml version="1.0" encoding="UTF-8"?> 
<CatalogItem> 
<RelationshipData> 
    <Relationship> 
    <RelationType>PAGEDETAILSINFO</RelationType> 
    <RelatedItems count="16"> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-20-GR1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-20-GR1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-21-GR2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-21-GR2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-30-JH1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-30-JH1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-31-JH2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-31-JH2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-20-GR1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-20-GR1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-21-GR2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-21-GR2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-30-JH1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-30-JH1" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-31-JH2" /> 
     <RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-31-JH2" /> 
    </RelatedItems> 
    </Relationship> 
</RelationshipData> 
</CatalogItem> 

XSLT, который используется здесь

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

Пожалуйста, помогите удалить duplciates

Вы можете использовать это:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> 
<xsl:output method="xml" indent="yes" /> 
<xsl:template match="/document"> 
    <CatalogItem> 
     <RelationshipData> 
      <Relationship> 
       <RelationType>PAGEDETAILSINFO</RelationType> 
       <xsl:variable name="pagetype" select="//attrGroupMany[@name = 'pagetype']/row"/> 
       <xsl:variable name="pagecontain" select="$pagetype//attrQualMany[@name='pagecontain']"/> 
       <xsl:variable name="pagewidth" select="//attrQualMany[@name = 'pagewidth']/value"/> 
       <RelatedItems count="{count($pagetype) * count($pagecontain) * count($pagewidth)}"> 
        <xsl:for-each select="$pagetype"> 
         <xsl:variable name="attr" select="attr[@name='pagemeasure']"/> 
         <xsl:for-each select=".//attrQualMany[@name='pagecontain']/value"> 
          <xsl:variable name="value" select="."/> 
          <xsl:for-each select="$pagewidth"> 
           <RelatedItem referenceKey="{concat('PAGEDETAILSINFO','-',ancestor::item/ID,'-',../../attr[@name='pagestate'], '-', . ,'-', @qual, '-', $attr , '-',$value, '-', $value/@qual)}"/> 
          </xsl:for-each> 
         </xsl:for-each> 
        </xsl:for-each> 
       </RelatedItems> 
      </Relationship> 
     </RelationshipData> 
    </CatalogItem> 
</xsl:template> 
</xsl:stylesheet>
