Re: [Simple-support] Inline list of simple elements with different names

[Jarrod S. <ja...@co...>]

Thanks Niall,

The XML response is of this form:

<FAIL>

      <A>Error relating to A</A>
      <B>Error relating to B</B>
      <C>Error relating to C</C>
       ...
      <ERROR>General Error Message 1</ERROR>
      <ERROR>General Error Message 2</ERROR>
      <ERROR>General Error Message 3</ERROR>
      ...
</FAIL>

But I don't know what the A, B, C elements are actually named, only
that they just contain text, and won't be nested.

I'm currently using an ElementListUnion which gets me halfway there,
but that still requires that I know what all the element names are
(which I can only find out by trial and error, which will take
forever). So I need a way to just parse the simple document format
above, and just chuck all the element values into a list, array,
whatever.

Below is basically what I'm using at the moment, you can see the
different types of error element names I've managed to discover so
far.

@Root(strict=false)
public class MyServerResponseErrorParser
{

	@ElementListUnion({
		@ElementList(entry = "ERROR", inline = true, required = false, type
= GenericAPIError.class),
		@ElementList(entry = "CONTACT", inline = true, required = false,
type = GenericAPIError.class),
		@ElementList(entry = "SIGNUP", inline = true, required = false, type
= GenericAPIError.class),
		@ElementList(entry = "PLAN", inline = true, required = false, type =
GenericAPIError.class),
		@ElementList(entry = "PAYMENT", inline = true, required = false,
type = GenericAPIError.class),
		@ElementList(entry = "PLAN_ID", inline = true, required = false,
type = GenericAPIError.class)})
	public List<GenericAPIError> errors;

}

@Root
public class GenericAPIError
{
	@Text
	public String error;
}


Thanks a lot,
Jarrod.
