다른 요소의 첫 번째 또는 두 번째 자손에서 발견 된 특정 자손 요소를 식별하는 방법

Question

MFRAC를 MSUB의 자손으로 식별하는지 제안하십시오. 여기

는 MFENCED (삽입 한 특성)을 신장 시키 후술 일부 시나리오 :

• MFRAC 발견하고 MSUB 아니며, 이는 다음 MFENCED 필요한 STRETCH
  속성 경우.
• MSFR의 FIRST-CHILD-DESCENDANT에서 MFRAC이 MFENCED의 자손이며 인 경우 STRETCH가 필요합니다.
• 입력 xml의 세 번째 MATH에서 두 번째 MFENCED에 STRETCH가 필요합니다. MSUB의 두 번째 하위 자손의 MFRAC 자손이지만 해당 MFENCED 내에서 MFRAC는 조상으로 MSUB를 갖고 있지 않습니다.

새로 추가 된 추가 설명 :

아래 MFENCED 경우 (발 자손 (이) 본 MFENCED) 상관 MFRAC 발견하고 MFENCED 스트레칭 수 여기서 MFENCE/조상해서는 안 때문에, 주요 MFENCE와 관련하여 FRAC은 하위 두 번째 하위 - 자손 아래에 있습니다. 명확하지 않으면, 나는 더 설명 할 것이다.

Answer 2

MFRAC가 발견되었고 MSUB에 속하지 않은 경우 MFTENED 속성 STRETCH 이 필요합니다.

MFRAC는 자손과 같은 MFENCED MSUB의 FIRST-CHILD-하위하에 다음 필요한 연신 찾으면

<xsl:template match="mfenced[.//mfrac except .//msub//mfrac]"> 
    <xsl:copy> 
    <xsl:attribute name="stretchy">true</xsl:attribute> 
    <xsl:apply-templates select="@*, node()"/> 
    </xsl:copy> 
</xsl:template> 

.

입력 XML, 2 MFENCED 필요 STRETCH, MSUB의 두번째 하위 후손 심지어 MFRAC 자손에서 세번째 수학

<xsl:template match="mfenced[.//msub/*[1]//mfrac]"> 
    <xsl:copy> 
    <xsl:attribute name="stretchy">true</xsl:attribute> 
    <xsl:apply-templates select="@*, node()"/> 
    </xsl:copy> 
</xsl:template> 

하지만 MFENCED 내에 MFRAC 그 조상 MSUB 갖는되지와 .

죄송합니다. 여기에 귀하의 영어가 명확하지 않습니다.
