XSLT XML을 새로운 요소 그룹 및 속성으로 변환하는 방법

Question

XSLT를 사용하여 XML을 변환하는 방법을 알아 내려고 애 쓰고 있습니다. 주요 목표는 XML 소스 데이터를 가져 와서 월 데이터를 기반으로 새로운 행을 반복/작성하도록하는 것입니다. 예를 들어, 현재 각 행에는 "X"양의 월 데이터가 모두 하나의 행으로 있습니다. 각 행마다 한 달 분의 데이터 만 포함 할 수 있도록이 문제를 해결하려고합니다. 다음 행에는 동일한 헤더 정보가 포함되지만 원래 소스 행의 다음 달 데이터는 포함됩니다. 다행히도 그것은 의미가 있습니다. 필자는 예제에서 볼 수 있듯이 해당 월의 숫자 값에 대한 새 값을 대상 XML 내의 새 값으로 트리거하기 위해 행의 월 열을 구성하는 방법을 알아 내려고합니다. 어떤 제안이라도 크게 감사 할 것입니다.

이 시도 :

<!--- you need to complete this variable with all month keys: --> 
<xsl:variable name="monthCodes" select="('JAN','FEB','MAR','APR','MAY','...')"/> 
<xsl:template match="Row"> 
    <!-- saves the month-total columns in a variable--> 
    <xsl:variable name="months" select="Column[contains(@name,'Month_Total')]"/> 
    <!-- groups the $months: starts a new group, if the @name is matching on the regex 'Month_Total$' --> 
    <xsl:for-each-group select="$months" group-starting-with="*[matches(@name,'Month_Total$')]"> 
     <Row> 
      <xsl:variable name="rowNum" select="count(../preceding-sibling::Row/Column[matches(@name,'Month_Total$')]) + position()"/> 
      <xsl:attribute name="rowNum" select="$rowNum"/> 
      <!-- copies all Columns of the current <Row> witch are not in $months --> 
      <xsl:copy-of select="../Column[not(contains(@name,'Month_Total'))]"/> 
      <xsl:variable name="monthCode" select="substring(@name,1,3)"/> 
      <Column name="{$monthCode}_Month_ID"> 
       <Val xsi:type="xsd:integer"> 
        <xsl:value-of select="index-of($monthCodes,$monthCode)"/> 
       </Val> 
      </Column> 
      <Column name="YEAR"> 
       <Val xsi:type="xsd:integer"><xsl:value-of select="year-from-date(current-date())"/></Val> 
      </Column> 
      <!-- copies all nodes of the current Row (the mont h-total columns of the current month) --> 
      <xsl:copy-of select="current-group()"/> 
     </Row> 
    </xsl:for-each-group> 
</xsl:template> 
<xsl:template match="node() | @*"> 
    <xsl:copy> 
     <xsl:apply-templates select="@*"/> 
     <xsl:apply-templates select="node()"/> 
    </xsl:copy> 
</xsl:template>
