输出: - 没有任何Null B,因为我需要在没有Null B的情况下根据此输出进行另一个映射

使用下面的数据编辑来检查xml的内容,但是将输出作为null B,请建议如何避免这种情况。因为我需要为每个元素做另一点指向从xml到xml的映射,但是Mapping正在创建一个额外的映射,其中B也是null。
请建议如何避免此
%dw 1.0
%output application/xml
---
A: payload.id.*items mapObject
{
B:$ when $.method=="valuelink"
otherwise {
}
}
&#13;
答案 0 :(得分:0)
下面应该有效。请注意,B:$由()封装,这意味着,仅当&#39;当&#39;时才包含此属性。条件是真的。
%dw 1.0
%output application/xml
---
{
A: payload.A.*B mapObject {
(B:$) when $.method == 'valuelink'
}
}
