yes i was doing something similar to get the variables. The problem is  the parsing of the element. I want to implement a generic parser for all the processes deployed on the console. But every process has its implementation of variables so i can't effectively know in what node is the variable data(some in the first child, some other in nested childs). 

if (variable instanceof MessageValue) {
  | 			MessageValue messageElement = (MessageValue) variable;
  | 			Map partElems = messageElement.getParts();
  | 			// Get the first Element
  | 			String partName = (String) partElems.keySet().iterator().next();
  | 			org.apache.xerces.dom.DeferredElementNSImpl partElement = (org.apache.xerces.dom.DeferredElementNSImpl) partElems.values().iterator()
  | 			.next();	
  | 			String valueVar=partElement.getFirstChild().getFirstChild().getNodeValue();
  | 		}

This code won't work for all processes because in another process this line will be :


I was thinking a node searcher/comparer to variable Name but i hope something simpler will come out...

any help is appreciated.
