[jdom-interest] Document.getContent() only returning the root element, not all xml child content elements as expected

[Jason Hunter]

Hi Julius,

document.getContent() returns all nodes directly under the document, 
which would be the root element and maybe some comments or processing 
instructions, and maybe a doctype.  It's not designed to iterate through 
the full document.  For that you can call document.getDescendants().  It 
gives you an iterator for all nodes matching the optional filter you 
pass it.
