XSL 변수 또는 매개 변수는 정의되어 있지만 파일

Question

에서 나는 오류가 발생 상속 XSLT 템플릿과 붙어 :

line 200: Variable or parameter 'child' is undefined. 

문제는, 어떤 변수 또는 매개 변수 "아이가"이 거기에 없습니다를 줄 또는 다른 파일 전체. "자식"에 대한 유일한 참조는 xpath에 있습니다. 여기

<xsl:with-param name="ancestor"><xsl:value-of select="$ancestor"/></xsl:with-param> 

을 내가 관련되어 있다고 생각하는 전체 부분 : 라인 (200)은 다음과 같습니다.

<xsl:template name="create_title_row"> 
    <xsl:param name="ancestor"/> 
    <xsl:param name="columnDepth"/> 
    <xsl:param name="pos"/> 
    <xsl:if test="$ancestor &lt; $columnDepth"> 
    <tr> 
     <xsl:for-each select="/mask/table[position()=$pos]/descendant::clmn[count(ancestor::clmn) = $ancestor]">    
     <xsl:call-template name="create_column">   
      <xsl:with-param name="ancestor"><xsl:value-of select="$ancestor"/></xsl:with-param>

     </xsl:call-template> 
     </xsl:for-each> 
    </tr> 
    <xsl:call-template name="create_title_row"> 
     <xsl:with-param name="ancestor" select="$ancestor + 1"/> 
     <xsl:with-param name="columnDepth" select="$columnDepth"/>

Answer 1

지금 (2018) 동일한 오류가 발생했습니다. 수입이없고 선은 매우 유사합니다. 오류가있는 줄은 다음과 같습니다.

<xsl:with-param name="ancestor" select="$ancestor"/> 

변수의 이름을 firstFather로 변경하면 오류가 사라집니다.

<xsl:with-param name="firstFather" select="$firstFather"/> 

저는 조상이 예약 된 이름이고 변수로 사용될 때 실패한다고 생각합니다.
