XML至对象MULE具有相同名称的重复节点

Question

I need to convert an xml to a java object in MULE.

<porto>
  <nome>example</nome>
  <nave>
     <x> a </x>
     <y> b </y>
  </nave>
  <nave>
     <x> c </x>
     <y> d </y>
  </nave>
</porto>

The problem I'm having is that I can't find a way with the "XML to Object" component to save the double "nave" component into the class.

I can't use Enterprise edition and can't change the xml. I can't use the JAXB approach either.

Answer 1

It doesn't work because the transformation creates a Java map with nave as the key, and because the key is the same one of the nave elements overrides the other. You will need to write a custom transformer for that.

Using DataWeave it is possible to write a simple script to do the transformation but it is not available in the community version.

Example DataWeave

%dw 1.0
%output application/java
---
porto: { 
    nome: payload.porto.nome,
    nave: payload.porto.*nave
}

Answer 2

I managed to solve the problem using the right annotation in the class:

@XStreamImplicit
private List<Nave> nave;
