Re: BIG PROBLEM

First of all thank you. The problem is that I do not have a file. I have only
the MessageElement array. I do not read any file, or build any document. From
that I can get the iterator, but it iterates through one attribute. I need to
expand that one. The essential part in youw code that I cannot use is:

Element rootElement = document.getRootElement();
Iterator elementList = rootElement.getDescendants(new
ElementFilter("element"));

Maybe you can detaliate more this solution.

                                                                  Stefan
