xml - 我的 SCORM 1.2 先决条件的有效文本节点值是多少？

Question

我正在尝试创建一个排序的 SCORM 1.2 包，其中包含多个模块。但指定多个项目标识符会创建无效的 XML。

从 ADL 的“The SCORM Content Aggregation Model”(转到第 2-139 节)中，使用的文本节点值为:

<adlcp:prerequisites type="aicc_script">R1&R2</adlcp:prerequisites>

因此 XML 在 R1/R2 之间的 & 符号上被阻塞。我可以使用什么来代替 & 字符？我尝试了一个逗号，它在 Moodle 中有效，但在 Saba 中无效。

我的 list 内容:

Answer 1

尝试使用&这是转义 & 符号的首选方式(另请参阅 How do I escape ampersands in XML so they are rendered as entities in HTML? )

(我刚刚在 LMS 中尝试过，它有效)
