转变API的第 2 个参数确保所有的空属性将不属于序列化XML的一部分。
The second argument of the convert API ensures that all the empty attributes are not part of the serialized XML.
如何结合在一个循环中序列号和空吗？
在去除编组之后的字段值将一直保持是空值，因为它的值没有被序列化或反序列化。
This field will always have the value null after unmarshalling because.
如果序列是空的，就返回初始值，否则函数会先接收初始值和序列的第一个元素，然后是返回值和下一个元素，依此类推。
In this case the starting value is returned for an empty sequence, and the function is first applied to the starting value and the first sequence item, then to the result and the next item, and so on.
