XSL : 특정 값의 각 인스턴스를 찾기 위해 카운트 사용

Question

나는 얼마나 많은 SIM 카드를 같은 사람이 구입했는지 알아 내고 그 번호를 고객 ID와 함께 출력하는 XSL 파일을 작성하려고합니다. 여기

은 관련 태그의 예와 XML 파일의 추출물이다 :

<sim> 
     <simID>16</simID> 
     <areaCode>081</areaCode> 
     <number>1234582</number> 
     <customerID>5</customerID> 
     <yearPurchased>2008</yearPurchased> 
     <monthPurchased>10</monthPurchased> 
     <dayPurchsed>12</dayPurchsed> 
    </sim> 
    <customer> 
     <customerID>5</customerID> 
     <surname>Brown</surname> 
     <firstname>Peter</firstname> 
     <streetAddress>103 Main Street</streetAddress> 
     <townName>Dorpborough</townName> 
     <countyName>Kilkenny</countyName> 
     <contractOrPrepaid>contract</contractOrPrepaid> 
     <confirmedIdentity>1</confirmedIdentity> 
    </customer> 

<sims> 및 <customers>

는 여기 태그 내에서 해당 태그의 여러 인스턴스, 같은 아이들과 함께 모두있다 내 XSL 코드 :

<table rules="all"> 

       <thead> 
        <tr> 
         <th>Customer ID</th> 
         <th>No. of Sims Purchased</th> 
        </tr> 
       </thead> 

       <tbody> 
        <xsl:for-each select="database/customers/customer"> 

         <xsl:variable name="customerIDvar" select="customerID"/> 

         <xsl:variable name="numOfSims"> 
          <xsl:for-each select="database/sims/sim"> 
           <xsl:value-of select="count([customerID=$customerIDvar])"> 
          </xsl:for-each> 
         </xsl:variable> 

         <xsl:if test="$numOfSims>1"> 
          <tr> 
           <td> 
            <xsl:value-of select="$customerIDvar"/> 
           </td> 
           <td> 
            <xsl:value-of select="$numOfSims"/> 
           </td> 
          </tr> 
         </xsl:if> 
        </xsl:for-each>   
       </tbody> 

      </table> 

정확하게 잘못하고있는 부분을 알아낼 수 없습니다. 특히 "numOfSims"변수입니다. 나는 일할 수 없다. 어떤 도움이라도 대단히 감사하겠습니다. 당신의 XML이 같은이라고 가정

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output method="xml" indent="yes"/> 
<xsl:template match="/"> 
    <table rules="all"> 
     <thead> 
      <tr> 
       <th>Customer ID</th> 
       <th>No. of Sims Purchased</th> 
      </tr> 
     </thead> 
     <tbody> 
      <xsl:for-each select="database/customers/customer"> 
       <xsl:variable name="customerIDvar" select="customerID"/> 
       <xsl:variable name="numOfSims"> 
        <xsl:value-of select="count(/database/sims/sim[customerID=$customerIDvar])"/> 
       </xsl:variable> 
       <xsl:if test="$numOfSims>1"><tr> 
         <td> 
          <xsl:value-of select="$customerIDvar"/> 
         </td> 
         <td> 
          <xsl:value-of select="$numOfSims"/> 
         </td> 
        </tr> 
       </xsl:if> 
      </xsl:for-each> 
     </tbody> 
    </table> 
</xsl:template> 
</xsl:stylesheet>

이 같은이어야한다

<database> 
<sims> 
    <sim> 
     <simID>16</simID> 
     <areaCode>081</areaCode> 
     <number>1234582</number> 
     <customerID>5</customerID> 
     <yearPurchased>2008</yearPurchased> 
     <monthPurchased>10</monthPurchased> 
     <dayPurchsed>12</dayPurchsed> 
    </sim> 
    <sim> 
     <simID>16</simID> 
     <areaCode>081</areaCode>

     <dayPurchsed>12</dayPurchsed> 
    </sim> 
</sims>
