Help with Jaxb - AnyType access to sub-elements?

[anonyusenet]

Hi All,

I am reading an XML file (defined with XML Schema) using Jaxb.

I need one particular element to hold an arbitrary, but well formed,
XML document (with any tags).

As such I've defined this element to be of the type xs:anyType.

The AnyType Jaxb class however only appears to be giving me access to
the text node strings (not sub-elements).

I need the whole thing so I can pass it on to another parser.

Any ideas? Is this supported in jaxb? Is this supported by XML Schema?
Am I doing something wrong?

See details below.

(Email me if you would like full source code)

Thanks!
mike

THE CODE:

// get the fields
String from = xmlMessage.getFrom();
String to = xmlMessage.getTo();
Calendar date = xmlMessage.getSendDate();
AnyType payload = xmlMessage.getPayload();

// print out the values
System.out.println("FROM: " + from);
System.out.println("TO: " + to);
System.out.println("DATE: " + date.getTime());
System.out.println("PAYLOAD: " + payload);

// print out details regarding the payload (The AnyType list)
System.out.println("\tAnyType list length = "
+ payload.getContent().size());

for (Iterator i = payload.getContent().iterator();
i.hasNext() {
Object o = i.next();
System.out.println("\t" + o.getClass() + " : \"" + o +
"\"");
}
