XSLT 피벗 동적 열

Question

을 나는 그룹과 피벗 입력 XML 데이터에 노력하고 JSON으로 변환하고있어, 나는 내가 dymanic 열 이름을 고려 무엇 이외의 작업의 대부분을 이 내 현재 XSLT이다

<?xml version="1.0" encoding="UTF-8"?>

          <xsl:text>":"</xsl:text> 
          <xsl:value-of select="@measResult"/> 
          <xsl:text>"</xsl:text> 
        </xsl:for-each> 
       </xsl:for-each> 
       <xsl:text>}</xsl:text> 
       <xsl:if test="position() != last()"> 
        <xsl:text>,</xsl:text> 
       </xsl:if> 
      </xsl:for-each-group> 
      <xsl:if test="position() != last()"> 
       <xsl:text>,</xsl:text> 
      </xsl:if> 
     </xsl:for-each-group> 
     <xsl:text>]}}</xsl:text> 
    </xsl:template> 
</xsl:stylesheet> 

는 다음의 XSLT의 출력은 다음과됩니다

파일의 샘플입니다 그러나 내가 열, 즉 "VSCEULMEANULGROUP"에서 값 누락 : "14.65"을, 그것 인을 사용하여 코드를 쉽게 정적 ColumnName 및 measResult (나를 위해 작동하지 않습니다) 또는 "VSCEULME 는 XML

{ 
    "root":{ 
    "Table":[{ 
     "TableName":"HH_CORE_BASE", 
     "Stamp":"2016-12-29T23:30:00-07:00",

Answer 1

짧은 대답에서 ANULGROUP가 "="14.65 "에 있다는 것입니다 :

<xsl:for-each select="@ColumnName"> 
    <xsl:text>,"</xsl:text> 
    <xsl:value-of select="."/> 
    <xsl:text>":"</xsl:text> 
    <xsl:value-of select="@measResult"/> 
    <xsl:text>"</xsl:text> 
</xsl:for-each> 

문맥하지 않는 ColumnName 속성입니다/measResult라는 이름의 속성을 가질 수 없습니다. 부모/포함 요소로 되돌아 가야합니다.

<xsl:for-each select="@ColumnName"> 
    <xsl:text>,"</xsl:text> 
    <xsl:value-of select="."/> 
    <xsl:text>":"</xsl:text> 
    <xsl:value-of select="../@measResult"/><!--CHANGED THIS LINE--> 
    <xsl:text>"</xsl:text> 
</xsl:for-each>
