#macro ( recursive $e $indent )

$indent <$e.name>
#foreach ($child in $e.elements() )

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

#recursive( $root.rootElement $i )


Next, we access pieces of data directly :

email : $root.rootElement.element("properties").element("author").element("email").text
last name :  $root.rootElement.element("properties").element("author").element("name").element("last").element("full").text
