SV: SV: moving an Element

Hi,

well, you could perhaps use a filter that hides the optional elements
in the getChildren call:

List children = this.getElement(parentIdref).getChildren(filter);

Or, better yet, perhaps you should build a proper object model, either
as a facade directly in front of your JDOM tree, or try a data binding
solution (e.g. Castor or JAXB).
