First, we print out the document tree with a
recursive Velocimacro :

#recursive( $root.getRootElement() $i )


Next, we access pieces of data directly :

email : $root.getRootElement().getChild("properties").getChild("author").getChild("email").getText()
last name :  $root.getRootElement().getChild("properties").getChild("author").getChild("name").getChild("last").getChild("full").getText()
