저는 XSLT에 조금 붙어 있습니다. 모든 자동차 광고에 대해 XSLT의 평균 가격을 계산하는 방법을 설명하고 있습니다. 우리가 자동차의 모든 유형을 볼 수 있듯이 XSLT를 계산하십시오.

그러나 평균 가격을 계산하지 않습니다,이
<xsl:variabel name="carsbelow19" select="format-number(count(ad[regyear <= '1999']), '0')"/>
<xsl:variabel name="carsabove19" select="format-number(count(ad[regyear >= '1999']), '0')"/>
처럼 자동차의 전체 수를 사용하여 다음이
<td><xsl:value-of select="format-number(sum(ad[regyear <= '1999'] div $carsbelow19), '0.00')"/></td>
하지만이 때문에 오류가 발생합니다. 그래서 나는 전체 variabel을 사용하고 기존 자동차를 "div"로 연결할 수 있다고 생각하지 않습니다.
누군가 해결책을 알고 있거나 올바른 방향으로 나를 가리킬 수 있습니까? 감사합니다.
'xsl : variabel'은 유효한 XST 요소 이름이 아닙니다. –
