我的 XSLT 为这个大学目录创建了三个级别的分组。我需要再添加一个级别来识别可选类并将它们组合在一起。
第一级组在第二级<ACPGAREAOFSTUDY1>组上<ACPGDEGREE1>和第三级组上<ICCB1>
第四级基于四个要素：<COURSEORAND1> <GROUPORAND1> <ACADREQMTBLOCKSID1>和<GROUPLABEL1>
这是最终分组的逻辑
当 COURSEORAND1 说“或”时，GROUPORAND1 为空。-这意味着有两个或多个课程可供选择，它会输出“OR”</p>
当 COURSEORAND1 说“OR”时，GROUPORAND1 说“AND”。- 这意味着它将为组中的 2 门课程输出“或”。这也意味着它将为组输出“AND”。
课程可以按元素 ACADREQMTBLOCKSID1 分组，这些组可以按 GROUPLABEL1 分组。
这是当前的 XSLT：
