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.
