Данные группы и количества

Question

Я работаю над тем, чтобы попытаться подсчитать количество баллов для каждого студента, основываясь на разных этапах проверки теста. Тест для оценки успеваемости состоит из нескольких уровней: оценка приложения, письменный тест, групповое интервью, интервью У меня есть подсчет на основе пола на каждом уровне.

Если вы используете процессор XSLT 3 (как показывает его использование xsl:iterate), вы можете использовать for-each-group с составным ключом группировки для заявки и теста, я думаю:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xpath-default-namespace="urn:com.student.report/student_test"
    xmlns:xd="urn:com.student.report/student_test"
    expand-text="yes"
    exclude-result-prefixes="#all"
    version="3.0">

  <xsl:output indent="yes" method="html" html-version="5"/>

  <xsl:template match="/">
      <html>
          <head>
              <title>Grouping example</title>
          </head>
          <body>
              <xsl:apply-templates/>
          </body>
      </html>
  </xsl:template>

  <xsl:template match="StudentData">
      <table>
          <thead>
              <tr>
                  <th>Student Requisition</th>
                  <th>Student Test</th>
                  <th>Male Pass</th>
                  <th>Male Fail</th>
                  <th>Female Pass</th>
                  <th>Female Fail</th>
              </tr>
          </thead>
          <tbody>
              <xsl:for-each-group select="StudentRecord" composite="yes" group-by="StudentRequisition/@xd:Descriptor, ProfileStudentTestGroup/StudentTest/@xd:Descriptor">
                  <tr>
                      <td>{current-grouping-key()[1]}</td>
                      <td>{current-grouping-key()[2]}</td>
                      <td>{count(current-group()[Gender/@xd:Descriptor = 'Male'][ProfileStudentTestGroup/StudentTest_Status[@xd:Descriptor = 'Pass']])}</td>
                      <td>{count(current-group()[Gender/@xd:Descriptor = 'Male'][ProfileStudentTestGroup/StudentTest_Status[@xd:Descriptor = 'Fail']])}</td>
                      <td>{count(current-group()[Gender/@xd:Descriptor = 'Female'][ProfileStudentTestGroup/StudentTest_Status[@xd:Descriptor = 'Pass']])}</td>
                      <td>{count(current-group()[Gender/@xd:Descriptor = 'Female'][ProfileStudentTestGroup/StudentTest_Status[@xd:Descriptor = 'Fail']])}</td>
                  </tr>
              </xsl:for-each-group>
          </tbody>
      </table>
  </xsl:template>

</xsl:stylesheet>

Если вы используете процессор XSLT 2 (который не поддерживает составной ключ группировки), либо объедините два значения или вложите две for-each-group инструкции.
