Take a look at the @Path annotation

Subject: [Simple-support] Interpret a sub-element as String

Hi,

Here's an XML I have:

<root-element>
    <description>lorem-ipsum</description>
    <sub-element id="1"><name>Hello World</name></sub-element>
</root-element>

Now, for whatever reason, I want to read the <sub-element> part as a String rather than as an object - i.e.,

@Root(name="root-element", strict=false)
class RootElement {
    @Element(name="description")
    String description

    //No @Element annotation here.
    String subElement;
}


RootElement root = new Persister().read(RootElement.class, INPUT);

RootElement EXPECTED = new RootElement("lorem-ipsum", "<sub-element id=\"1\"><name>Hello World</name></sub-element>");
assertEquals(EXPECTED, root);

Similarly, when I serialize this RootElement object, I want the string to appear as a sub-element.


Any idea on how to go about doing this? It looks like I am looking for some sort of interceptor - I get the partially parsed object and then I can fill in the missing fields.

I tried using a Converter and the @Convert annotation; I tried implementing a Visitor - in both cases I got stuck trying to figure out what portion has been parsed already.

I have temporarily written code to first parse the object with all fields except subElement; and then set this field using sub-string operations. However, this is not really scalable - especially when I use sub-element inside a list, inside other parent elements, or when root-element itself has other parent elements etc.
