使用XSLT在循环中条件匹配时向元素添加元素

标签： xml xslt

我正在尝试在XSLT 1.0中实现这一点，以下是条件 在任何时候，ADT的发生都不仅仅发生在INF一个ADT应该只有INF标签的一个姓氏，名字和DOB细节 如果ADT标签超过INF标签，则应将第一个ADT标签标记为INF，并且如果ADT标签不应附加任何INF，则应休息。不需要更改子标记，但它应该出现在输出中。

我正在尝试使用XSLT实现以下输出，但无法完全修复它，任何帮助都将非常感激。

在XSLT下面需要帮助进行转换

输出中有几个小故障。 <firstName>的{​​{1}}和<surname>的值互换。成人的INF也不在输入中，但在输出中显示。如果输出中需要<middleName>，则可以对以下XSL进行必要的更改。

XSLT 

<middleName>

输出
