Question

我正在尝试在我的XSLT中创建一个类学分的总和，但我无法弄清楚在何处放入sum语句。

这是我创建的总结声明：

   <credit-sum><xsl:value-of select='format-number(sum(CRSMINCRED1),"##")'/></credit-sum>

数据分组三次：

1. by Area of Study
2. By Degree
3. By Requirement or Elective status

我想仅仅总结“必需”类的学分。但是当我把sum语句放在其中时，只是单独显示每个类的总数而不是类组。

这是XSLT：

Answer 1

似乎CourseCroup模板是进行此更改的地方：

  <xsl:template name="CourseGroup">
    <xsl:param name="courses" />
    <xsl:param name="title" />
    <xsl:param name="requiredCourses" select="false()" />

    <xsl:if test="$courses">
      <xsl:text>&#xA;</xsl:text>
      <req-electitle>
        <xsl:value-of select="$title" />
      </req-electitle>
      <xsl:apply-templates select="$courses">
        <xsl:sort select="FlagElectives1" order="ascending" />
        <xsl:sort select="CRSSUBJECT1" />
        <xsl:sort select="CRSNO1" />
      </xsl:apply-templates>
      <xsl:if test="$requiredCourses">
        <credit-sum>
          <xsl:value-of select='format-number(sum($courses/CRSMINCRED1),"##")'/>
        </credit-sum>
      </xsl:if>
    </xsl:if>
  </xsl:template>

然后你只需要修改第一个call-template来添加一个额外的参数：

  <xsl:call-template name="CourseGroup">
    <xsl:with-param name="courses" select="$courses[FlagElectives1 = 'N']" />
    <xsl:with-param name="title" select="'Program Requirements'" />
    <xsl:with-param name="requiredCourses" select="true()" />
  </xsl:call-template>
