In the unformatting process, it is not required to define the data element. You can use a dynamic data element instead of predefined data element. Following is the sample code to unformat the dynamic data element:

public static void main(String[] args) throws Exception {
KeyedCollection dataElement = new KeyedCollection();
dataElement.setDynamic(true);

FormatElement format = FormatFactory.getFormatElement("PersonFormat");
WriteAdapter write = new DataElementWriteAdapter(dataElement);
byte[] bytes = HexCodecUtil.decodeHex("06C785969987850400000012".toCharArray());
Message message = new Message(bytes);
format.unformat(message, write);
System.out.println("====Unformat Result====");
System.out.println(dataElement);
}

====Unformat Result====
<kColl id="" dynamic="true" compress="false" >
<field id="name" value="George" description="" />
<field id="age" value="18" description="" />
